• A horde of 50 headcrabs leaded by the artificial inteligence and which grow each time a player join the server.
  • Headcrabs can zombify at any momments the players (who play as combines) to become zombines.
  • After that the players succed to annihilate 50 headcrabs, the boss headcrab make their enter in the game
  • HE grenades and knifes do instant kill against headcrabs
  • Respawn and an optional infinite ammo avaible
  • Musics from Half-Life 2 played each round.
  • Fully customizable.

In this Counter-Strike Source mod, the goal for the players who fight as combine soldiers is to annihilate the horde of headcrabs leaded by the artificial intelligence. For this, they must kill the whole horde (+50 headcrabs) and then kill the king headcrabs. During each round, the number of headcrabs spawned in the map is equal by default to the number of players in the server plus three. So for instance, if there are 5 players connected on the server, then the mod will spawn 8 headcrabs in the opposite team ! Of course this number can be modified by admins

When the players finally manage to annihilate the headcrab horde, the king headcrabs make their entrances in the game. They are monstrous over sized headcrabs who can endure a lot of damages before dying ! And the worst of all, it is that despite their size, they are as fast as you ! So even if the normal headcrabs are easy to kill, few bullets and you are done with them, the king headcrabs will need a new tactic to defeat them.

But there is also another thing that make Headcrab Mod more stressful ! Each time a player is being attacked by an headcrab, he can suddenly being transformed in a zombine (everybody know that headcrabs jump on heads to control their victims?) ! So be careful when one of your team mate is attacked by headcrabs ! You might see him the first time shooting on the head humpers, and then the second time running at you with a crab on his head and in hurry to shred you in small pieces. This always add more stress since any friendly player can become your worst enemy at any time !

The mod is bug free and does not make problems, the admins can easily configure it. Also, the mod is compatible with almost every other scripts, allowing you to add more functionalities to make your server unique. Even if I don't work any more on this mod but I might complete it one time. I have already planned to port the original Gonnarch from Half-Life 1 into Headcrab Mod to be the final boss (followed with many King Headcrabs of course !). There will be also a new rank system which will, for instance, sphmn as an elit combine the players who have the best KD/Ratio in the server or as a metro police those who have more deaths than kill.

It is now more than a month that the full mod is available to download. Despite all my attention and my tests, there was some bugs and gameplay problems which was still left, and since the release of the mod, I did my best to fix it. Today, even if some minor bugs may still occur the mod is mostly free from errors.

While the main campaign is completed, I still have many maps and content on my computer that I had decided to cut during the development of the mod because I knew it would be taking to me too much time to implement it. However, now that I am done with the main campaign, I can try to finish this cut content and to add it to the mod as a "Secondary Campaign" in order to extend the gaming experience and the life time of the mod, so that it could reach about two hours of playing ! I shall post some screenshots of the work in progress soon.

Else, the mod is now available and supported on Desura, so if you have this platform installed you can directly install and play my mod !

Thank you for reading this ! Remember that if you enjoyed the mod, don't hesitate to rate it !

Personally, I think that zombies become bored to kill because you always need nearly 5 clips of hundred bullets to kill one of them, especially with Zombie Mod.

At my advise, zombies should always being more than humans, and should have always low health and low speed. Also, zombies should NOT being controlled by an human players (who prefer being a zombies rather of a survivors?). If I have added a zombie mode to Headcrab Mod, it is only to prevent from unfair camping ;)

The best part of every FPS game this decade distilled to its essence: backing up from spiders-like creatures while shooting them. Everyone loved that part in Unreal 2

I simply give to him 10.000Hp, make that he goes very fast(but you can config all these settings at any time) and make that he spawn one time at the end
