Playtapus, the enemy isn't invincible. Just send multiple submarines, helicopters, and the other one that's got AA guns o.o I took them down to like, 6000 or 5300 or sumn with just those. Just be careful if you send helis. The enemy has anti aircraft guns. If you're gonna send em, send a huge convoy. Anyways, to the comment. I love this game. There are multiple things you can improve on. Like the background. Why is it blank? Can't you add some war stuff like on the cover or something? It'd make the game much more fun, and a little harder. Also, I'd like to hear some gunfire in the background. I also think the bases should be on actual land. Other than all that, this game is amazing. 9/10, 4/5!
