I don't normally write reviews, but this game is so utterly crap that I feel I have a responsibility to warn others about it. I set out looking for a good RTS, with a simple and descriptive interface. I did not find that in Perimeter. All I found here was a confusing and boring game with few options and limited controls. Not only are there no descriptions or tooltips for units or buildings, but you only get a limited number of builders, which you have to distribute as either ground maintenance (they call it terraforming, but it's more like watching slow, old ladies working in the garden) or building builders. Seriously, you only get like 5. Another thing is that your army turns into a blob of tiny pixel-units. Your whole army becomes basically one unit. Even if you have multiple objectives on a mission, you have one blob-unit to take care of everything. Or maybe I'm stupid, and just couldn't figure out how to split them into smaller armies, but as I said before: this game lacks in descriptions, instructions and tooltips. The story is original, but you just can't make up how horrible the gameplay is. I was so frustrated with this game that I dove right back into searching for a good RTS that I forgot to get my money back for this thing. At this point, I just wish I could remove it from my library.
