We are the Xenoborgs.
You will be assimilated...Well cut in half with a nasty, instakill laser and then assimilated.
Hated those freaks, awesome enemy, in a way, but I hated them.
There were some big flaws with the idea both plot-wise and gameplay wise:
1.They kill you instantly
2.Why wasn't their laser made into a usable gun?
3.It made no use of the aliens abilities, all it did was stumble around like a regular borg and shoot a laser, the laser did all the killing not the xenoborg, you may as stick a laser on the head of anything...
4.How the hell would an Alien mistake a clunking, 10 ton cyborg armed to the teeth with death lasers for another alien.
Nah they shouldn't be put in this game, IMO it doesn't really fit that well with the universe.
