Directive: Survive

Directive: Survive is a tactical mobile game in which you manage two defenders against waves of enemies in short episodes.
The main challenge of the game is to do multitasking under pressure.
The game features 3 damage types, and enemies correspond to one of these damage types. The player must also be swapping which type of damage their units are using to be able to fight off the enemies.
To aid the player in the game, there are power-ups assigned to the units and the level that can dramatically affect how quickly units can defeat enemies or prevent enemies from reaching the gates as quickly.
