I once saw this awesome game at a friend of mine, called Tactical Ops. It was awesome, but it was hard to find on the internet. I finally found the download, but I found out the URL broke today. I didn't find any other downloads, so I decided to upload it on my own website(thought it requires a good amount of webspace)! :D
The game was simply too awesome and derpy, I had to do it. Even if it has the graphics of a cow, it runs on almost every hardware.

So here it is! The original game download!

Have fun with it!

NOTE: It's for windows, version 3.1.5. Patches are still on the internet somewhere!
