Monster War 3DM

Starting like a simple cartoonish like game, it rapidly develops into something serious, and your enemies will become a threat!
On each level, you will have up to four different types of weapons (bullets, grenades, deadly bullets, and shells) and a variety of enemies to defeat.
Sometimes, you will not have enough ammo, sometimes you will not have enough time, and always you will have an overwhelming enemies.
You will have to use different approaches to pass. Sometimes, you will have to shoot as crazy, sometimes you must be cold-blooded and precise. 
Everything is just like you like.
Don't worry, you can do this. There are 50 levels in total. Some levels are a nightmare, some levels are OK.
Enjoy the game!
