Madness....
This was a pretty great First-Person-Shooter(FPS).
The guns were very detailed and the graphics were amazing for a game on Newgrounds. Even the game play ran with almost no flaws. Now for the intresting part, I had used only four weapons: Kimber, UMP, M4A1, and the almost sniper M14! The only problem I saw was the fact that the aiming reticle was a little off but I am surprised you did even that well with what you had. Although the aiming was a little off here and there it was almost realistic because lets face it you wont be able to get a head shot every time on a moving target from a distance with a pistol. My Score was around 32010 and I got to wave 30 I think.
Now for the tips:
1. Always get a Delta Sniper.
2. Stock up on grenades to about 15.
3. Always make sure to have Air Support.
4. Always repair after (don't use unless you need Air Support, then fill health as far as you can).
5. Always aim for the weak spots on the enemy.
6. Save up and don't buy anything until you can buy a SMG or Rifle (like the UMP or M4A1).
7. Buy the upgrades! Along with equipment. At the very least both pouches, one of the belts, and the light vest.
If you use these tips you should at least get to wave 25.
