I find this game very fun,because unlike other games where you can upgrade your weaponry and such in this game you can actually upgrade the entire game from graphics to backgrounds and even the menu buttons.So very good game 10/5
Add a minigun or 50. cal nests around the map for some of them or traps would be awsome as well.And it would also be very cool if you added items such as a beserk or rapid fire or unlimited ammo.
