I understand if this is just a test version...
When you make the new version it would probably be a good idea to add some ducking features and new weapons, and for now the game is incredibly short, just some advice.

WHAT
i can't kill middle guys 2nd round i shot him like 1000 times he doesn't die!!!!!!! no replay value either
Could have been great.
Next time test it before you post it. The third guy up there can't be killed, missing code. I had fun for about 2 seconds, then I died 'cause I couldn't kill the guy. I hope that next one is better, 'cause this one was way too sloppy.
Good Start
Testing the waters is always a good start to things. I like where your going with it, hope to see it more full.
