GunGame being included in CS:GO as Arsenal Mode is pretty cool and all… but we all know there’s one CS server mod that is much more popular and, possibly, more enjoyable. Just like GunGame, it’s made its way to all sorts of third-party games across all sorts of platforms, but its home will always be right here. Perhaps even more so, in the future!
"Gamma Energy" is a mod for Portal which revisits the troubles of Aperture Science. The mod is a great unofficial expansion for Portal which is well written and designed and highly recommended for anyone who is a lover of the original game and it's style of puzzles.
