Many, many years ago there was an FPS on a PC called Blake Stone. You were a secret agent sent to the base (on the moon I think) to infiltrate it and see what were the baddies up to. It turned out that the baddies were buddies with some alien creatures. You would walk around the base and shoot almost everything. Almost, because some of the researchers were good fellas and would give you money or snacks. The gameplay was very similar to Wolfenstein 3D, and there were also secrets looked for by pushing walls. I loved this game. Loved, loved, loved! And I would love to find it. Do you know if it was ever published for Amiga and if it was possible to find it today?
