Pocket Troops is a fun mix of a Fallout Shelter "base"-upgrading and troop training game, and a squad-based strategic shooter.

We train our troops, equip weapon and armor pieces, expand our base, and take on campaign and "multiplayer" battles (not actual multiplayer; we fight another player's troops, controlled by AI).

I love the games humorous story and art style, but my main frustration is that we have to wait for soldiers to revive if they die in battle, which is how the game monetizes (plus through selling special troops acquired for premium currency).
