It's been said multiple times that they aren't going to reveal anything about the Alien gameplay until closer to the release date.
Personally, them keeping the Alien gameplay "on lockdown" is quite exciting, because IMO it means they have something pretty spectacular. (or, it sucks and they don't want to piss people off yet lol)
And um... one question. Why have 2 wristblades if you're only going to use one?
I also love how they had to make him unable to die so they could get him through the mission. His health bar drains quite quickly from the fall and the initial alien strike, but then once it gets to one bar, he hits the tree with his plasma caster and hurts himself, no damage, gets hit a few times by the bugs, no damage, hit more by acid, no damage. Lol.
