Complete junk, total waste of space. Original UFO is still the best version to date.
Graphics are pretty dated, and sound is pretty junky as well. Gameplay which as always, is the most important and makes or breaks a game is almost completely lacking, the problems in game are just too numerous to mention ranging from Aliens popping up into thin air and attacking through to occasionally 'crash to desktop' problems.
Just avoid this game unless you want trashy and ultimately annoying gameplay.
