An unknown enemy attacked a military base! You barely had time to notice how all this happened, you were stunned by a strong explosion, after which you lost consciousness. When you woke up in an unknown place, you found several units of an unknown weapon. It seems that it can come in handy if you find ammunition for it. The door to the next floor is locked, you need to find the key card to open it. Try to survive and destroy the unknown enemy. Good luck!
