Level 1	Level 2	Level 3	Level 4-5
Level 6-7	Level 8	Level 9-10	Level 11-20

---

• Summary
  • The Machine Gun is the third defense to unlock in the game.
  • The Machine Gun is very effective against large groups of Riflemen or Warriors.

---

• Offensive Strategy
  • Deploying Heavies in front of Riflemen or Zookas is a very effective way of protecting them from Machine Guns. However, although having just one Heavy can protect Zookas, one Heavy will not protect Riflemen. This is because the Machine Gun is so inaccurate it usually misses the Heavy and hits the Riflemen.
  • The closer your troops are to the Machine Gun, the more accurately it fires. If possible try to destroy it from a distance.
  • Although Warriors can be chewed up if attacking a Machine Gun directly, they can easily heal through the occasional bullet if they are attacking something else at the edge of the Machine Gun's range.
• Defensive Strategy
  • Machine Guns are very effective front line defenses as it stops weak troops like the Rifleman or Zooka from making it into your base.
  • Placing Machine Guns near Boom Cannons can help prevent large numbers of weak troops from destroying it.

---

• Upgrade Differences
  • Initially, the Machine Gun is a green gun mounted on a silver stand, and there are two silver handles on the back.
  • At level 2, the Machine Gun gains a small pile of sandbags. There is also a small magazine on the back, and the front of the barrel becomes smaller and ridged.
  • At level 3, the magazine on top is removed, and instead, there are two magazines, one on each side.
  • At level 4-5, the Machine Gun gains a larger pile of sandbags. It also gains a reinforced handle and frontal shield. The side magazines are removed, and the whole barrel becomes thinner.
  • At level 6-7, a disc is added on top of the back of the Machine Gun, behind the shield.
  • At level 8, the stand is reinforced and the barrel loses its ridged pattern and now has holes in it.
  • At level 9-10, the Machine Gun loses all its sandbags. It gains a stone base, a modified handle system, and a bigger and more reinforced frontal shield which covers the entire gun and is more angular.
  • At level 11-20, the Machine Gun gains a back shield and loses its handles, becoming hexagonal.

---

• Trivia
  • It fires 10 shots per second making it the second fastest shooting defense in the game, after the Flamethrower.
  • Machine Guns were invented in the mid 19th century and have been used in war to this day.
  • The Machine Gun undergoes more changes per upgrade than any other current building.
  • The MMG 9000 is similar to a high level machine gun with two short barrels. Despite its looks, this defensive structure is capable of killing a decent amount of troops if not taken out quickly.

Cannons

"Cannons fire powerful, large caliber shells towards one target at a time. This makes them ideal against heavy and armored enemies, but less effective against massed infantry. Deals double damage to tanks."

---

Level 1	Level 2-4	Level 5-9	Level 10-20

---

• Summary
  • The Cannon is the fourth defense to unlock in the game.
  • The Cannon is a single target defense that deals high damage to one unit.
  • The Cannon deals double damage towards Tanks.

---

• Offensive Strategy
  • Cannons deal massive damage to one unit, so be careful of them.
  • Take advantage of Cannons placed too close together and use a Shock Bomb on them to allow your Troops to take them out easily.
  • If possible, use Flares to flank around and avoid as many Cannons as possible.
  • In low level Warrior attacks, Cannons are one of the most dangerous Defensive Buildings. They will pick off your Warriors one by one. Try to destroy any Cannons with Gunboat Weaponry or shock them as your Warriors come in range.
  • When using Tanks, it is suggested to destroy most, if not all, of the Cannons and Boom Cannons with Gunboat Weaponry such as Artillery or Barrages, before deploying the Tanks.
    • When Artillery and Barrages become too expensive, try using a Shock Bomb and a Flare on it to allow your Tanks to destroy it unharmed.

• Defensive Strategy
  • Cannons are your main defenses against high health Troops at low levels and remain important for many levels, so try to protect them well.
  • Try to upgrade your Cannons as much as you can to give them more health and help prevent attackers from destroying all or most of your Cannons with Gunboat Weaponry.
  • Place your Cannons behind other Buildings so that the Cannons get a chance to shoot many times.
  • Check for obvious paths through wide open sides of your base that someone using the Heavy-Zooka army composition may use to flank around your Cannons. Keeping such areas protected with Rocket Launchers and/or Sniper Towers will massacre the Zookas after the Heavys walk by which ruins the attack.
  • To help defend against Warrior rushes, your cannons should be the second closest buildings to your Headquarters. Cannons can be very effective at killing groups of Warriors.
  • Putting you Cannons near the front lines can be very effective at defending against Tanks. It makes the Tanks face them before they have gathered enough energy to destroy the Cannons with Gunboat Weaponry.
  • Keep your Cannons spaced out so that attackers cannot shock many at once.

---

• Upgrade Differences
  • Initially, the Cannon is a green structure with a medium sized barrel, a metal base, and a valve at the back, with an "80" drawn on the side. (see trivia below)
  • At level 2, the barrel gains an orange band around it.
  • At level 5-9, the Cannon's base becomes more reinforced, and the cylindrical tube becames more hexagonal.
  • At level 10-20, the Cannon's barrel gets much longer, and is surrounded by better metal plating, with larger orange highlights. A second very thin barrel is added on top of the main barrel.

---

• Trivia
  • The Cannon is the second most dangerous defense (besides the Boom Cannon) against high health troops. They are likely to be taken out with Artillery and Barrages before the troops are deployed.
  • The number on the side of the Cannon is different than the number in the same place on the other side. One side says 08 while the other side says 80. It is unknown why these numbers are different. It may be a visual mistake by Supercell.
  • Although the Cannon does double damage to Tanks, if both Tanks and other troops are in its range, it simply targets whichever is closest and doesn't prioritize Tanks.

Mortar

 

"The Mortar is an artillery piece that is effective at medium to long range, but can't target enemies right next to it. Mortar shells explode and deal damage to all troops in the area of effect."

---

Level 1-2	Level 3-4	Level 5-7

Level 8-15	Level 16-20

---

• Summary
  • The Mortar is the second defense, and the first splash damage defense, unlocked in the game.
  • The Mortar has medium DPS and has a long reload time.

---

• Offensive Strategy
  • The Mortar is very effective against massed infantry, so be careful of them when using Riflemen or Zookas. A few Artillery shells from the Gunboat will make short work of it, allowing Riflemen and Zookas to have an easier time destroying the base.
  • Mortars are very weak against Warriors, as the Warriors are melee troops and attack from inside its range, and move fast enough that they can easily avoid Mortar shots. Warriors can also outheal the damage dealt by even two or three Mortars of equal level.
• Defensive Strategy
  • The Mortar is an extremely effective defense in the removal of large groups of low-health troops such as Riflemen or Zookas. Placing the mortars centrally in your base and protected by other defenses can help your defenses succeed.
  • It is usually a good idea to put Mortars near the back of your base so Warriors have a hard time reaching them.
    • It may also be a good idea to put your Mortars near the front of your base. When Troops move up, the Mortar shot is likely to hit Zookas in the back which can ruin an attack.
  • Its good to have your Mortars in range of your Headquarters. Mortars are good at working with Rocket Launchers and Flamethrowers to destroy groups of rushing Warriors.

---

• Upgrade Differences
  • When initially constructed, the Mortar is a tube-like structure that is on a round green rotatable plate, which is fitted in another golden hexagonal plate.
  • At level 2-4, the middle part of the rotatable plate becomes golden color.
  • At level 5-7, the tube becomes longer and the sides of the hexagonal plate become silver. The base of the Mortar is now armed with a handle that has a cogwheel in the middle.
  • At level 8-15, the tube gains a circle metal brace and the tip gains two stripes of golden coating. An additional handle appears at the base of the Mortar. The base is reinforced all around.
  • At level 16-20, the tube becomes much wider and appears to be made completely out of bronze. The handles are removed and replaced with large screws. The inside of the base becomes circular and bronze, and the outside is further reinforced.

---

• Trivia
  • Some of Lt. Hammerman's bases feature a Super Mortar 3000, a stronger and longer-range Mortar with no blind spot.

Boom Cannon

 

"The Boom Cannon fires devastating shots but takes a while to reload. Even the strongest armor is no match for the Boom! Deals double damage to Tanks."

---

Level 1	Level 2-5	Level 6-9	Level 10	Level 11-14

---

• Summary
  • The Boom Cannon is the sixth defense to unlock in the game.
  • The Boom Cannon is one of the strongest defenses in the game and is very effective against high health troops, such as Tanks or Heavies.

---

• Offensive Strategy
  • When attacking Boom Cannons, be sure to either destroy them upfront with a Barrage or Artillery, or limit your time in range of them without them being shocked. A Boom Cannon picking off your large units can ruin an attack.
  • Boom Cannons have a long reload time, so they can easily be taken out by a group of small troops.
  • It is possible for Tanks to avoid the shots of a Boom Cannon on the opposite side of the Headquarters unless it is right up against the Headquarters. If there is even one space between the Boom Cannon and the Headquarters, your Tanks will be out of range on the opposite side if you maneuver them correctly.

• Defensive Strategy
  • Once a total of 4 Boom Cannons are available, it is effective to place them in a diamond or square formation in your base well distanced so that it covers as much of your island as possible.
    • On the other hand, you may want to place them all close to your Headquarters to prevent attackers from avoiding certain Boom Cannons entirely simply by attacking the base from the opposite side.
  • Do not place your Boom Cannons in front of all your other buildings like many people do. Boom Cannons are most effective when they are able to take advantage of their long range and target attackers' troops for long periods of time.

---

• Upgrade Differences
  • Initially, the Boom Cannon is a gray structure with a stone base surrounded by sandbags. It has brown plating, valves on both the side and the back, as well as a long barrel.
  • At level 6, the Boom Cannon gains a thicker barrel and slightly darker colored plating and barrel. The sandbags around the base are removed.
  • At level 10, the Boom Cannon gains a metal base, an even thicker barrel, tubes at the back, and darker colored plating.
  • At level 11, the Boom Cannon gains a heavily armored base.

---

• Trivia
  • The Boom Cannon is the slowest-firing of the single-target defenses, but causes the most damage per shot of any defense (with the exception of the Boom Mine, which is a single-use item).
  • Although the Boom Cannon does double damage to Tanks, if both Tanks and other troops are in its range, it simply targets whichever is closest and doesn't prioritize Tanks.

Sniper Tower

"The Sniper in the tower shoots at enemy attackers. He's armed with a long-range rifle that deals good damage."

---

Level 1	Level 2	Level 3	Level 4-6

Level 7	Level 8-9	Level 10-13	Level 14-20

---

• Summary
  • The Sniper Tower is the first defense to unlock in the game.
  • The Sniper Tower is a long-range, single-target defense that deals medium damage.

---

• Offensive Strategy
  • The use of Flares is a very effective way of targeting this building.
  • Using Shock Bombs can temporarily disable them, preventing them from further damaging your troops. 
  • Sniper Towers can be easily overwhelmed by large groups of troops, but it may result in fewer casualties if your infantry is shielded by a Heavy.
• Defensive Strategy
  • Sniper Towers are most effective when shielded by buildings as they can take advantage of their long range, making it more difficult for troops to target them.
  • They are most effective when spread out. When clustered together, they can be disabled by a single Shock Bomb, rendering all of them useless.
  • Sniper Towers are only dangerous when supported by other defenses. While they are lethal anti-infantry turrets, this power comes with a relatively slow rate of fire of 1 shot every 1.4 seconds, which can be easily destroyed by even a small group of Riflemen if no other defenses are in range.
  • Having Sniper Towers cover the sides of your base can prevent attackers using the Heavy-Zooka from flanking around your defenses. The Snipers will kill the Zookas after the Heavys have walked past which ruins the attack.
  • When trying to defend against Warrior rushes, your Sniper Towers should be the third closest defense to your Headquarters with Flamethrowers and Cannons being the closest and second closest respectively. Sniper Towers deal enough damage fast enough to deal with Warriors fairly well.

---

• Upgrade Differences
  • When initially constructed, the Sniper Tower appears as a tall wooden lattice structure with its front support protected by three sandbags. A short wooden ladder is attached to the side of the structure.
  • At Level 2, the Sniper Tower gains more sandbags on the top as a fortification, except on the side where the ladder goes up.
  • At Level 3, the Sniper Tower gains extra protective sandbags around the base, and the sandbags on the top of the tower are replaced with a wooden fortification.
  • At Level 7, the Sniper Tower gains a corrugated metal roof, metal sides, and stone structural supports at the bottom. The color of the entire building changes to green.
  • At Level 8, the Sniper Tower's base is filled in with stone.
  • At Level 10, the Sniper Tower's roof becomes flat, and the wooden pillars and the ladder become metal.
  • At level 14, the Sniper Tower's base becomes reinforced steel and replaces the sandbags with stone studs.

---

Trivia The level 7 upgrade introduces stone bases on the legs and requires Stone to complete, while the level 10 upgrade turns the pillar and the ladder to metal and requires iron to complet

Headquarters

At Boom Beach, its a war game. You only need to destroy the headquarters(The main nucleus). Once you destroy headquarters , every single thing in the island like defensive buildings, production buildings, storage buildings, vault, any buildings will destroyed and you will earn victory points. You need victory points in order to rise to a new level. I will pronounce headquarters to HQ. I hope you are fine with that. So once you upgrade your HQ, more defensive buildings and other buildings can be built. If your buildings is in max level and it says"YOU NEED TO UPGRADE HQ ", you must upgrade HQ to upgrade HQ to maximum level which is lvl 20. After upgrading HQ, you will get new buildings. Ok...thats all for hq. I will be showing more guides . Cya later :D.
