Awesome game, just a few suggestions...
1. Make the guns easier to aim with. The Militia has that placement for a reason. Make the Militia guns better to shoot from afar with.
2. Add. More. Guns. They don't need to be lying around, just make them so you have a few more choices!
3. Allow a scope. Otherwise you use your binoculars and when you go back to gun mode, they're already gone!
4. CROUCH! I see a LOT of cover that allows your head to be seen, with results with: Instead of normal hits, you get killed by head shots! It's the perfect way to fake cover so people can kill you BETTER!
5. You can climb on roofs. That is just wrong. If you allow us to climb, make it a button or add a ladder.
6. You need WAY more maps. This gets quite boring with just one, and now people are at the point where they find bugs in the map and use them to become potentially invincible.
All in all, this game rates a 4/5.
