Depth Charge: Sea Division

Take control of a all army ship and fight against submarines and whatever they fire in your direction. You can play the game in Campaign or Survival mode. Campaign mode is based out of 36 unique levels, while Survival mode tests how long you can survive and how much subs you destroy in that time. If successful, you can upload your score to global scorelist and compete against other players. If you feel like you’re stuck in a level, you can always upgrade your ship or buy special powerup with in-game money that you get the money after every battle.
