"It's payback time! Tell me where your puny base is, and I will crush it!"


  • This event is unlocked after having built the Weapon Lab.
  • In this event, Lt. Hammerman will appear in a Gunboat north west of your home base on the Archipelago, and you must defend your base against his attack.
  • This event starts at 6 a.m. for your time zone every 7 days and lasts for 21 hours. Note that Daylight Saving Time will affect Hammerman Strikes Back event times.
  • To win the event, you must successfully defend your base against Lt. Hammerman's attacks.
  • The event is made up of seven stages. Each stage is harder than the last.
  • Each stage awards one or more Prototype Modules and Intel if you successfully defend your base.


  • Every Monday, Hammerman appears for the event.
  • In this event, Hammerman attacks your base.
  • There will be seven stages in Lt. Hammerman's attacks, each stage being tougher than the last one, similar to Dr. T.
  • To begin a stage, tap on the Gunboat labelled as "Hammerman's fleet" that is located near your home base on the Archipelago map.
  • Tapping on his Gunboat will display an info box containing the following information:
    • The Prototype Modules you will receive for winning the stage.
    • The troops he will use in the current stage and their level.
    • The Statue bonuses that will buff his troops for the stage (if any).
  • To start the stage, press the "Defend" button found within the info box. You will then be able to watch Lt. Hammerman attack your base.
    • The cost to begin a stage is equal to five times your Attack Cost.
  • If you successfully defend against Lt. Hammerman in one stage, you will receive the Prototype Module reward for that stage, and then the next stage will become available to defend against.
  • If Lt. Hammerman's troops successfully destroy your Headquarters, you can retry and defend again against the same troops.
  • Each stage's troop configuration, statue bonuses, and troop deployment locations will be the same for everyone.
  • You will have 21 hours to defend against him as many times as possible. There is no limit to how many times you can attempt to defend Lt. Hammerman.
  • If you successfully defend against stage seven, you complete the event, and Hammerman will leave until the next event in seven days.

The Attacks

  • When Hammerman attacks, he will send up to 4 waves of 8 Landing Craft of troops.
  • For Hammerman to win, he must destroy your Headquarters.
  • Hammerman will use Gunboat Weaponry.
    • He can use Artillery, Barrages, Shock Bombs, and Critters, with the latter two only being used in stages 6 and 7 of his attacks.
    • He will always aim at the center of a building. This means he will not take advantage of the Artillery's ability to equally damage multiple buildings.
    • He will always target the same building(s) with Gunboat Weaponry on successive attempts of the same stage. This means that after your first attempt of a stage, you can move the targeted buildings aside so that the Gunboat Weaponry does not affect your other buildings.
    • He uses Gunboat Weaponry at the beginning of each wave while deploying troops; he will not support troops with Gunboat Weaponry until he deploys his next wave of troops.
  • The troop deployment locations for a stage are fixed. This means that if you retry a stage, he will deploy each wave of troops in the same place that he did last time.
  • For you to win, you must either defeat all of the troops that Hammerman deploys or keep your Headquarters safe until time runs out.
    • If you fail a defense but defeated part of the troops in one try, these defeated troops come back in the next try, so it is all or nothing.

Defensive Strategy

  • General insight is the player's best chance at surviving a wave. When toggling Hammerman's Gunboat to initiate an attack, be sure to preview the Troops he plans to bring along with him, and their order from left to right.
    • Troops that are dropped off first can be planned for, such if Hammerman chooses to load off an entire wave of Zookas first, it would be best to place splash damage defenses such as Rocket Launchers and Mortars so their range intersects with the beach.
  • Rifleman swarming is a pretty popular tactic of Hammerman's, and it is very difficult to deal with, especially when Medics are a part of the equation. Wherever one plans to eliminate hoards of Riflemen altogether, place a neat and organized row of Mines in their path. The multiple continuous strikes are not likely to be healed before the Riflemen die.
  • If Hammerman decides to deploy a wave of Grenadiers ahead of all other combinations, it is best to throw every Boom Cannon and a Shock Launcher, coupled with a few Sniper Towers at the beach head. If the player feels the next wave will be a hoard of Riflemen, plop these long range defenses nine to eleven tiles away from the shore and place Boom Mines at the head of the beach instead.
    • Notice: Shock Launchers should never cover the beach when a hoard of Riflemen are expected to be brought first. If a hoard of Riflemen survive before the next wave lands, the next wave will receive those shocked Rifles as their cover. The only exception is if Rocket Launchers attack the first wave of Riflemen in unison with the Shock Launcher and no Medics are present.
  • Take advantage of Hammerman's AI. If you spy him Barraging a defense of your's down, put it off to the side in the next attack and rid any mines away from its proximity.
    • One could take advantage of this knowledge and place it in a position where it is likely Hammerman will use his GBE on it when his Troops pass around the targeted building. This is especially useful when clearing an unstoppable swarm of Riflemen.
  • In the case of a Warrior rush right off the bat, sacrifice any economy building (usually one to three for the lower stages) in their path. If Riflemen do not follow, place regular Mines around the front of the bait buildings. Warriors should not make it to the second line.
  • To take advantage of any strategy of Hammerman's, maximize the amount of time it takes him to clear all of your buildings and start aiming for the Headquarters. This is made easier to the player due to the fact that Lt. Hammerman does not use Flares.
    • This can be done with a variety of base layouts, but is particularly attainable with any variant of a sweep base, where all buildings create a wrap around the side of the base, follow to the rear of the island, and cycle back to the other side.
    • Notable features include a front line that begins at the shore of Hammerman's first chosen landing side on the beach and long range defenses such as Rocket Launchers and various Prototype Defenses placed in the center of the island.
  • If you have attempted to defend Hammerman and failed, but know that a lot of Riflemen were left at the end of the attack, you could place a line of Mines at the back, behind most of your defenses but in front of the HQ. Be sure to redirect the remaining Riflemen in a manner such that they would move to the next building in the formation of a line to maximize the effectiveness of this strategy.
    • One of the most effective formations for these Mines would be a checkerboard pattern; the Mines at the back will finish off the Riflemen that are heavily damaged from the first impact.
    • Placing a spare Boom Cannon next to the HQ in that case could be critical to the success of a defense. If a few Riflemen survive the line of Mines, the Boom Cannon can pick them off one by one before any more damage could be done. The Boom Cannon is also integral if the player wishes to stop Tanks that may have been protected by the mass of Riflemen.
    • The strategy may be less effective if Hammerman uses Critters on your main defense on the last wave. If your defenses are heavily crippled and he starts his fourth wave while placing Critters in the area of your main defense, the Critters could move in front of the Riflemen and trigger some of the Mines, which were critical to defeat the mass of Riflemen in the first place. The same is true if his last wave contains Warriors or other fast troops.
    • If the layout is poor, Grenadiers may render the strategy ineffective if they manage to hit the Mines while attempting to hit a building in front of the Mines. To avoid this, ensure that the distance between the last line of the main defense and the line of Mines is as large as possible.
  • Understand when to stop initiating attacks. If the player struggles but manages to wipe out Hammerman's attempt at 4, and at stage 5 the player is absolutely obliterated, it is highly unlikely that any formation of the base is capable of defeating the stage. Wasting Gold needlessly is not in the player's interest.


  • Hammerman's attacks do not count toward the Strategist Achievement. They instead count toward the Hammer Down Achievement.
    • Similarly, his attacks will not be counted as attacks or raids (or both) in the "Daily Summary" part of the Activity Log.
  • There's an achievement which is called Hammer Down that gives a total of 175 diamonds upon victoriously defending against a total of 40,000 troops in the Hammerman Strikes Back event.
    • Note that this achievement counts the number of troops, not the housing spaces of troops. Even one scorcher counts as one.
    • The number of troops are counted by the ones that are deployed, not the ones that you killed. If you win by time out, you're still awarded the full number of troops deployed.
    • The criteria of this achievement are incorrectly translated in several language settings of the game.
