Headcrab Frenzy!

Headcrab Frenzy is a free dynamic action Half-Life mod which allows you to quench a desire to destroy these little bouncy critters to your heart's content, hold records, get achievements, and try your hand at cooperative gameplay, competing in public statistics. Two game modes, six maps, several headcrab types and gradually increasing "frenzy" scale which can be periodically vent - that's the crux of the mod. Is it casual? There is no doubt. But that's not so simple. To achieve high results and score more points you'll have to resort to various tricks: make combos, ensnare headcrabs, use power-ups (there are four in the game), and prevent other players from scoring, pushing them away by a secondary attack of your crowbar. Each map has its own tricks. By discovering them, you'll find out more ways to get high scores and take the first place in tournament tables!
