X-COM: Apocalypse - the third game in the series X-COM, released by MicroProse. Is the last part of the classic series UFO. Has significant differences from the previous two parts. One of these differences - the opportunity to play in real time mode. That, in general, does not prohibit the devotees stepping mode at any time to switch to it. Also, X-COM 3 uses SVGA graphics, which was certainly a qualitative achievement.
