Downloaded the demo of this game last night. Due out 17th of September and not sure of the price. Be fairly standard, I'm sure.
Someone looked at what was wrong with HALO (as most of us have) and fixed it. Spent less than an hour on it before and I'm chomping at the bit to get back to it.
Good squad gameplay. Not reliant on your squad but good team work will win the round. No spawn kills in this one unless you come in too hot or balls up where you aim. You spawn like a meteor and can either come in light and deploy your 'chute' (or whatever the fuck slows ya down by hitting 'A' on the xbox controller) at the moment they tell ya to or you can wait and land closer to the ground. You take damage that way but there's less chance of you being spotted but you can heal yourself as well.
There's all your standard kits like sniper, assault, engineer, etc, but there's a couple of extras like guardian where you can unlock a mech to stomp round in and blast away with or if you get close enough to the enemy you can pick them up by the skull and slam the fucker. lol GREAT fun.
If you didn't like HALO (or do but...) but liked the concept of exo-skeleton soldiering I reckon this one is worth a look. Online multiplayer and I didn't have ONE ISSUE with lag. And my internet is shit. Download the demo, it's free after all.
 Best AI I've come across too. You think you're playing against humans. *cough* So that kinda makes my lag comment before redundant. No idea on the lag...yet.
