This is a very tactful map. As soon as I spotted it, Counter Strike was the first thing that came to mind. It definitely has the CS feel to it. This would be a good deathmatch or team deathmatch map, and would only be good for human players, as the bots aren't tactful enough to hide, but just run out in the open where anyone can shoot them. Probably would be a more fun map to play on team deathmatch, using a team speak program such as Skype to talk with your teammates. Although rail gun would be the primary weapon for this map, it would still be pretty fun to use a rocket launcher as well. Excellent lighting and textures. 10/10.

There are lots of remakes from CS and its quite popular. I have downloaded a bigger and better version of the map.. Download Here!

Totally thrilling map. I love it! Gets a 10!

Didn't enjoy this one too much. LAN play is probably good though. A little open and item placement is not too good.

5/10
