I was really looking forward to this game! Guess I'll have to find another way to stay frosty.

Too bad it was cancelled. One of the Obsidian devs, Anthony Davis, let out a few details what the gameplay would have been like.

"The little guy next to the Alien is for scale genius. This was a concept piece.

The Xenomorphs according to canon absorb some dna traits from host creatures. The two in question here were the behemoth, taken from a very large herbivore, and the second was something were calling a stalker, essentially an Alien that can cloak like a chameleon, taken from a chameleon type creature host. There were also Queens, scouts, soldiers, spitters, and more - including black and red variants for those who know the material.

The game was most certainly NOT a grind fest. Experience was awarded for completing objectives and stealth was greatly encouraged.

Basic gameplay was your party was composed of 3 to 4 members. Party members could be from 1 of 4 different professions, marine, agent, engineer, and ugh...I forget the 4th at the moment .

In addition to stealth, party members could place traps for Aliens, such as turrets, mines, door bombs, and more. Doors could also be welded or cut to slow down Alien movement and create bottlenecks.

There was research, crafting, base defense and much more in the game and working." -Anthony Davis

What the cuntsack! A game that I was looking forward to and it gets killed.

Don't know if this is what you were going for, but I couldn't read the first line of this without seeing Homer toss a scarf over his shoulder.
