I am stuck!

[master of disaster]

Yo, I am new here. I have one question. At the moment I am playing Penumbra, I guess it is Requiem, and I got stuck. I came to some room where is some computer with email that says some codes of some rooms. I have to find some card that is used for opening some doors. Can anyone tell me how and were to find that card?

Sounds Like Tech Penumbra (i could be wrong, never played Requiem yet, still on black plague.) [Spoiler] Anyway, I belive theres a door next to a steam leak (the three pipe steam leak) theres a pot thing pick it up and mix both the acid and the thing you just picked up then go melt the lock at the start, i could be wrong if its Requiem.

Yes! It's Tech Demo. It's been a long while i last time been playing it, but i remember the card can be found at the starting room inside one of the lockers. Use the acid to break the lock as Xsdsdds said.
