A few pictures of the Greybox made for "Test Chamber Alpha"

This describes a scientific test chamber with a broken incubator in the center (one of those big glass tubes that usually houses an alien or clone or whatever). To enter, a blast door (a heavily reinforced metal door) is lifted open with machine assistance. The incubator is empty, seemingly broken with force from the inside. A green-ish ooze covers the floor around the break. Computers lie on tables on either side of the incubator. The keycard needed to unlock the unlock blast door from the keycard scanner is on the table to the left of the incubator. In the lower left of the room, some kind of acid ate away at the air grate leaving an openening with a green-ish ooze around the edges. To leave, the keycard must be scanned, causing the exit blast door to lift open.
