You would think more games would be 3D. I did like how this wasn't 3D in that other sense of the word. CGI games are something most people take for granted nowadays, so it's nice to see high quality stuff like this. I couldn't help but be reminded of the "Doom" games. This wasn't as good as them (including the popular flash "Doom" game here), but good. I especially thought the aliens had good designs.
My only complaint is that it took awhile to mow these guys down! At least you got a really nice collection of cool weapons to use. Even the name is fairly cool, if a bit cliched. It really seems like something you see in a game from the 90's. Not that that's an insult, most games are worse.
