heya. if you like action halflife, you should give the specialists a try. it's just like AHL, except it's more matrix themed. there's a great kungfu system. you can customize most all weapons with flashlights/laser sights/scopes/silencers, in any configuration you want. there are dives, rolls, flips (land on your feet or land in a slide), flip off the wall, backflips. awesome slowmotion effects. check it out:
