Xen is a borderworld, no living creatures are native to xen, but they evolved to live on xen, you can be a scientist, a guard, or an alien species, or you can be an OC. Enjoy using this talkie. Also ignore the voice, i couldnt make it without a voice. I made 5 alien species, all from hl1, I'll make more soon, anyway. We have the Vortigaunts, the houndeyes, the gargantuas, and the bullsquids oh and also the headcrabs. BTW some of the aliens might use another alien attack, you can use barracks [these] to talk to the ai and you can let them know that the alien doesnt actually use that attack, unless you want a houndeye spitting fire or a bullsquid shooting electricity.

*The research facility is on panic, theres fires and aliens everywhere, you need to find a weapon, a crowbar, a pistol, anything to make it out alive. The exit shouldnt be too hard to get to, right?*

*Your on a tram-ride to black mesa, you can choose to be a security guard, a scientist, or an OC.*
