The base game was fantastic. Never could say no to a game on dm-morpheus. But what really made it great for me were the total conversion mods.
I spent probably thousands of hours playing Infiltration back in the day. I can't imagine how much time and energy must have been poured into completely re-doing a game like that.
That’s a name that brings back memories. Infiltration was so far ahead of its time, and it’s interesting to look at how many of its features are now standard on even run-and-gun FPS these days.
