The most frustrating part of this game is the uneven difficulty. Most of the levels are sleepers, but then occasionally a level will come that lets you get 90% through and then just whomps you. And since it only saves at mission start, you get to do the whole thing over.
There is a fair amount of variety to the gameplay between the three different races, but playing against the same enemies for the whole game does take away from that. There's also so many different quirks to the frequently changing controls that I was constantly checking back on whatever keyboard configuration screen happened to apply to the current stage.
The graphics are passable; they neither add nor detract from the gameplay. The cut scenes are good for some light chuckles, but don't provide a very compelling reason to be slogging through yet another set of enemy barracks.
