I picked up the full game yesterday afternoon, and I gotta say its a home run!! I played all three different species, but fell in love with the predator. He by far is the most lethal in the game, and in multiplayer. I played some species team death match, then some Predator hunter,.. then finished off the Predator single player game off last night.
This game is so much like the original in so many ways, but so much better. In the species team death match, if the Predator can run and find his weapons really quick, the other species are screwed unless they work together and stay in groups. Like I suspected in the demo, the alien can't pounce really far and have a massive attack. I saw an option where you can turn on the growth cycle, I am assuming thats where you start out as a face hugger and work up,.. but in the games I played you start out as a regular alien.
Over all, great game and the game finding is much faster then the demo was. This game is more based for multiplayer, since each species single player is only good for 5 to 6 hours tops.
