Decided to try the game out because of the screenshots and I really like the alpha of this game. It reminds me of Marathon, one of my favorite first-person shooters, especially with the Pfhor-like alien raiders, the terminals with lore, the health recharging stations, and the futuristic revolver. I recommend slowing down the speed of the shielded alien raiders because they move a little too fast for the first enemies encountered.
Absolutely rad game, would play on my PowerPC Mac, 5/5 stars. Keep up the good work.
