Totally crazy modification made by russian G-Man fans or... err... haters! XD
Featuring: G-Mans (g-men?) are EVERYWHERE! They're invading our dear planet and trying to kill you... And now... YOU CAN KILL THEM! Yeah! :)
But don't be surprised when you see their appearance... He-he... >: )
Flying G-Mans, cyborg G-Mans, monster G-Mans, alien G-Mans...

This mod doesn't include any new maps or weapons. Just models, sounds and sprites. Should be compatible with any HL version (if you remove DLLs).

Have fun!! ~X~.

:notice: Also recommended for playing: X-Half-Life: Deathmatch

Enter the Gordon Freeman's nightmare...

G-Invasion in actionG-Invasion in actionInvasion continues!

Watch your back... err, front, and sides too! G-men are attacking! They walk, fly, crawl, teleport... Stop invasion, make a RIGHT final choice!
Start with the hazard(ous) course. And don't forget your briefcase!

A word of sanity: this is a total conversion mod for Half-Life 1, except there are no DLLs or maps. We wanted to turn original HL world into insane g-world and also prove that there's much can be done without coding and mapping (which also makes this mod compatible with almost any HL version).

* Now for both WON and Steam!
