WOW!
THAT sucked, I dont know why but if you make these things for a living, quit. No point, no complexity, and I still dont know why i take damage for shooting the guys. The other thing is that it has no relation to HALO and your shields don't Recharge. So what, you may say/ gives us a challenge. HA!!! why give someone a challenge of pointless holding the button and pushing forward.
MY SUGGESTION: make a better one with more story(not too much) and better gameplay. Oh and some mints if you have some.
