Release date: june 2014
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 and try your hand at cooperative gameplay, competing in public statistics. Two game modes, four 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!

There is full Linux support! You can play Headcrab Frenzy under Linux if you have a native Linux version of Half-Life.
You can play on the official Headcrab Frenzy internet server (see below).
Results of matches completed are published on the statistics page (

Official ModDB page:

This mod is completely free.

  • You start game with 5 lives. Every time you die, you may respawn, until your lives are zero. If they are, the game ends.
  • When you kill 40 headcrabs, you gain extra health points.
  • When you kill 100 headcrabs, you gain extra life.
  • Your health is regenerating with the rate of 2 hp/sec. The faster you move, the faster the regeneration process is.
  • Maximum number of alive headcrabs increases over the time.
  • Headcrabs' health and damage increases over the time also!
  • Killing several headcrabs very fast results in a COMBO!
  • Combo temporarily increases you crowbar's damage, the higher is combo - the longer is increase.
  • When you kill headcrabs, you gain "frenzy". Combos give additional "frenzy" points.
  • If your "frenzy" is full, you may activate it with reload key, and do 16x damage!
  • First crowbar swing does full damage, subsequent do the half.
  • Secondary attack of the crowbar is more powerful, but is slower. The amount of "frenzy" points got for killing by such attack, depends on weapon's upgrade value. If the secondary attack doesn't kill a headcrab, it pushes him away. It is also possible to push away other players!
  • Every minute your crowbar is slightly upgraded - it does more damage and "frenzy" mode lasts for a longer time.
  • If you kill headcrab tracking you with anything but you crowbar, you get an extra score!

  • Ladder - different headcrab types are spawned sequentially.
  • Random - all headcrab types are spawned randomly. Ladder mode goes into this mode after all types are spawned.

  • Invulnerability - player is physically invulnerable for all damage types.
  • Invisibility - headcrabs don't attack a player although still track him.
  • Regeneration - health regeneration is 3 times faster (6 hp/sec).
  • Lightning – while attacking, the crowbar periodically makes an electric discharge to the nearest target. The discharge has chain effect stacking up to 8 targets.
Powerups last for 20 seconds. They respawn in 1 min plus-minus several seconds in a single player game. There may be powerups of the certain type on maps, or a random powerup - it may be different on every respawn. Server may turn powerups off or tweak their respawn times.

There are 4 maps in the mod. After completing a level and learning the score, press Space in several seconds, and there would be a map change.

In a singleplayer mode, your highest scores are saved locally. High scores are stored individually for each map, game type and difficulcy level (Easy, Medium, Hard).

Start the game after all players are in. It also can be restarted (using a hcf_restart command). To restart an internet server, use a spectator vote system (press DUCK, then VOTES, then select a restart vote in the menu).

Your multiplayer score is published on statistics server (only if you play on a public server, see below). Player is identified by his Steam ID. Please note that your score is published ONLY if you complete the level (either all players are dead, or a 10 min time limit is hit), and server performs a level change.
