Possibly the weirdest platformer I've ever played. Very bizarre levels. The quality and variation between levels have massive differences, so I assume that different people worked on different levels. Some are terrible, some are awesome. The ending was the strangest thing I've ever seen in a video game. GOG version has no music (other reviews claim that there is music but it is absolutely broken), in either case some fan made a fix, if you experience the same issues download it and extract it and the music will play properly then. 7/10
Combat is good, level scenarious and layouts are good, music is superb. Speaking of expansions, Spearhead is only slightly weaker than main game, meanwhile Breakthrough while I like it, it is definitely not as good. Why did they make it so hard? On easy difficulty setting you barely get ammo, for some reason in this expansion enemies almost never drop ammo even though they always did in the main game and the other expansion. There was even one mission which I ran out of ammo for all weapons an had to use melee for maybe one third of the level. Also, the healpacks are rarer than checkpoints... Why did they make this expansion so difficult??? Overall, I enjoyed my experience much more than it annoyed me. I prefer Call of Duty 1 over this, but this isn't far behind. 7/10
