Gman Invasion

for Half-Life

28th April 2006

Sci- Fi Single Player First Person Shooter Games Half Life 2 Doom 3 Far Cry Unreal UT2004 Quake Mods

This is a Single Player Half-Life modification which replaces all the NPCs so they will look like G-Men. It also replaces some weapons and provides new features and some new Easter eggs.

Final Notes:

The mod itself uses the standard HL maps, it only replaces all NPCs so they will look like G-Men. It also has some new weapons and new Easter eggs, like the modified Xen and some modified sounds;)

    Hehe always wanted to kill Gman and now I get the chance to kill him how many times I want xD

  6. Perhaps somebody should make a mod where you play as the G-man and can control and kill anybody and everybody!

    I played this MOD through and it was no different than Half Life at all…no g-men. What happened? Oh wait, the levels were renamed.

  19. M0rt@nius

    That means you didn’t install it properly

    Very, very enjoyable up to where it crashes out just before you get the laser weapon. I played v1 first and the weapon mods make it for me. The pistol fire rate is speeded up alot which makes it very enjoyable to fire. Unfortunately the weapon mods seem to be removed in v2.2 which is why I didnt finish it.

    this game is the weirdest mod iv EVER PLAYED!but I thought it would have its own story not the HL story

    Good mod, but it’s recommended to play the latest version, 2.5 ATM. There are more fun things + bugfixes (almost no bugs except crashing on final titles, lol).
