Oh so much to say... first off in the description it says "Battle against Aliens, Robots, and Zombies in this futuristic fight." I'snt that EXACTLY what Halo is? But that doesn't really matter too much, this is great game. the weapons are great, there is a good variety of weapons without having too many. I love the rocket shoes they are very cool. Also the ragdoll physics are awesome, dying isnt too bad since you get to watch your dead lifeless corpse flail about as it falls hitting random objects. But there are some issues tho, many a times a times i'd angerly watch the rocket I just shot go strait thru an enemy. this also happened with other projectiles too. another annoying thing is that there is no target thingy to replace the normal cursor. aiming at aliens with a white arrow is lame. overall tho this a good game and deserves badges.
It really bugs me that this is the number 1 action game. Its not even action game! It's more of a strategy game!
Also I think this game kinda stinks, all u do is press 4 buttons, 2 of which (fallback, defend) you never use. So basically you press attack and march a bunch of times. how is that even considered actual gameplay? Sure the upgrades are great but there is no real action. Has is got to the point where us gamers value an elaborate upgrade system over fulfilling gameplay?
