Second Wind
"Temporarily revives fallen troops. Latest casualties are revived first. If there is not enough capacity to revive a large troop, Riflemen appear instead."


  • Second Wind is a Hero Ability available for Dr. Kavan starting at level 3.
  • Second Wind revives defeated Troops, spawning them near Dr.Kavan.
    • Seekers, Crystal Critters, Rocket Choppas, Heavy Choppas, Critters and MegaScorcher are not subject to Second Wind.
    • Revived troops will glow purple, and do not register as additional troops. They behave similar to the original, carrying the same stats & behavior (Scorchers, for example, will still run around erratically and skim over targets, blowing up if destroyed), will obey Flares, and can even be healed.
      • Much like Critters, revived troops will stand still during retreats. They persist until the battle ends, or if they are destroyed, being lost permanently upon the attack's conclusion.
    • Second Wind prioritizes reviving recent casualties, and will not resurrect the same unit more than once. For example, if two Heavies and two Zookas are defeated in that order and the ability is used at level 1, Dr. Kavan will revive two Zookas and one Heavy.
    • Second Wind only revives a certain amount of valid troops based on its own and their capacity, and will spawn Riflemen to fill up any remaining space.
    • Any troops spawned by Second Wind do not count toward casualties when destroyed.
  • Each use costs 10 more Energy than the previous one, with a starting cost of 8 Energy.

Offensive Strategy

  • Using the Second Wind ability to start a battle with extra Riflemen can bolster your army for the entirety of the attack, especially if your army already includes Riflemen and the ability was sufficiently upgraded.
  • In the event of a retreat, Second Wind could be used to revive fallen troops who will stand around distracting turrets while your main forces escape.
  • In the event you lose an important troop in your attack, such as a Medic, you should activate the ability as soon as possible before others could take its place. This matters more the larger it is, such as Scorchers, Tanks, Grenadiers and the aforementioned Medic.
  • Second wind can be used to revive defending troops from bunkers. This makes it an exceptional useful ability if bombardiers are present.
    • It should be noted that these troops can take up housing space instead of your own defeated troops.
    • Additionally, the garrisons present in the bunker will be summoned twice if the bunker and units inside are defeated.
