I am on the second part I guess. it has a food dispenser you can select ood from and a vending machine right by the red card door. there is also a bathroom right there. I have killed everything but I don't have the red card to go on. I back tracked to the door that takes you back and still no key card. where is the keycard at?
Isn't this the part where you need to repeatedly cycle through the food conveyor belt until the keycard appears? Someone says this to you earlier on in the level.
Later the same level I've encountered a huge burning hole in the ground and I'm told to find the blue keycard and a switch to the secret lab. I've found the blue keycard but can't seem to find the switch. Could somebody please give me a hint or tell me where it is? Thanks!
