I REMEMBER The alien being able to hug walls wats the buton to press ti hugg walls
I see you figured out it was left CTRL.
I can't remember how to get out of there anymore. Just keep a mental image of where you are and where you've been and try to go everywhere. I remember it took me a long time to find it.
Sadly, that's just the first time I couldn't find my way. There are a lot of maps where I kept getting lost. Finally, I just quit. MP is fun. SP, not so much.
