I just thought I'd share some interesting points from the preview. If I'm just repeating information you already know then please close this thread.
Melee Attacks"Melee attacks fall into a rock, paper, scissors style arrangement: your heavy attacks will break a block, a light attack can counter a slower heavy attack, and a well-timed block can stop a light attack in its tracks. Training yourself to recognise the animations, we're promised, will be key to winning fisticuffs, though here the Marine is at a disadvantage, as he can't use heavy attacks. Instead his penchant for ranged attacks redresses the balance".
Marine Finishing Move"Marines can block Alien lunges and counter with their own one-hit hill - a balls of steel neck-grab followed by a body slam and a few well-placed rounds to the skull."
Multiplayer ModesSurvivor - "Survivor pits marines against waves of aliens"
Infestation - "Sees a squad of marines fighting a small contingent of player-controlled aliens in a match where, once killed, marine players are resurrected as part of the alien team. Once the marines are whittled down to a single plucky soldier, that player's given a huge cache of weapons with which to make his last stand"
Predator Hunt - "Here, just one player is permitted to step into the skin of the master hunter, and must string together as many brutal murders as possible before he's stredded to bits by miniguns. Once that happens, control of the predator is handed over to whoever finally swatted him"
I just thought I'd point out a couple of niggles that PCZ noticed. They mention that the animations look a little rigid. They are also concerned with whether it will balance, but at the moment they say it's difficult to gauge. On a plus note, they say playing each race feels truly powerful!
