A wide-ranging Half-Life 2 (opens in new tab) mod called MMod, which has been in the works for nine years, is out now, and it reworks Valve shooter's visuals, gunplay and enemy AI.
Combat is the focus, and the mod adds new weapons, changes weapon handling, and introduces new animations. I'm a big fan of the new idle weapon animations that you can see in the trailer above: when stood still, Gordon Freeman will wipe the scope of his crossbow to clean smudges, or lovingly stroke his trusty rocket launcher.
As for new weapons, the video above shows that you can grab a turret and haul it around, spraying down enemies. You'll also be able to aim down sights on some weapons, such as the basic pistol.
The mod redesigns both the audio and visual effects, and tweaks the graphics in general. It certainly looks prettier than what I remember of the original—I like the new glowy eyes for the Combine soldiers—and particle effects are far flashier.
MMod also "hardens" the AI and gives the Combine new actions to perform, such as firing underslung grenade launchers.
It's already garnering praise over on its ModDB page (opens in new tab), where you can download it. Make sure you have a clean install of Half-Life 2 and both Episodes 1 and 2, as well as the free community-made Half-Life 2: update (opens in new tab), which the mod runs off.
Thanks, Dark Side of Gaming (opens in new tab).
