What Is This Thing?

Jabroni Brawl: Episode 3 is a massive collection of game-modes, maps, and weapons, built by an enormous group of modders using the magic of the Source engine. First started in 2012 (though development has been off and on!), JB3 expands upon what made the Half-Life mod scene great by combining ideas and concepts from various Half-Life 1 and 2 mods, such as Rocket Crowbar, Scientist Hunt, Jaykin Bacon, and many more. In addition, this game seeks to pay tribute to Valve's vast library of games, as players will be treated to an assortment of maps and player models taken from or inspired by various Valve games. We've also thrown in our own original ideas, and content from other random games we just enjoy, with the end result being a chaotic but (hopefully?) fun online deathmatch experience.

In 2018, against all odds, we obtained an engine license directly from Valve. Thanks to that, we are now operating off our own modified branch of Source, using the CS:GO engine as a starting point. Yes, that means this is now technically a Source game, but it’ll live on in our hearts as a mod forever regardless.

Huge thanks to Valve for helping us make this absurd vision a reality.

What's It Got?

Our game-mode selection is pretty extensive, and draws inspiration from many HL1 mods:

  • Battle Royale - Based off and expanded from it’s appearance in the 2004 Half-Life 1 mod Jaykin’ Bacon, each round begins with every player being given a random weapon. The last player standing by the end of the round will be the victor. Additionally, random KOTH-style safe zones appear at round-end to funnel players together, thereby ensuring the round doesn’t just end in a draw. Mutators can also kick in for random rounds, and serve to wildly change the rules to help keep long games feeling fresh (EX: A mutator round where you can only use a certain gun, or another mutator where you can only move backwards).
  • Sneak Vs Terrorists - Pits a team of heavily armed terrorists against a small stealth-oriented team (the Sneaks) who will be attempting to reach an objective that the terrorists must protect. A wide variety of gadgets will help Sneak reach the goal undetected, or silently take down members of the opposing team.
  • Sneak Vs M… - This pits a handful of Sneaks against a much larger team of shrunken-down melee players. They may only have their fists, but they’re fast and can respawn over and over again in their endless quest to kill the Sneaks. At least one Sneak must survive the horde for 90 seconds to be victorious! The appearance of team M also randomizes each round to feature a different “M” named group, just to keep things interesting (Sneak vs. Mattresses, Sneak vs Mallcops, etc).
  • Instagib - You spawn with a variety of 1-shot-kill weapons, but despite the visual differences, the fire-rate of these guns are all identical. The variation simply comes from what happens to a player you shoot with one of the gun (explodes, flies away, solidifies, etc). Pick a favorite gun, and score the most kills to win the round!
  • Gungame - Make your way through all the JB3 guns, getting a kill with each to progress. First to clear all the guns wins!

With over 80 weapons in so far, you’ll find plenty to keep yourself entertained. Here's a sneak-peek of what to expect:

  • Revolver - A powerful gun with an added quirk of always ricocheting after initial impact.
  • AX74 - It's an AKS74 with an Axe attached to the barrel. Shoot when they're far, swing when they're close!
  • Cardboard box - Duck or prone and don't press any of the movement keys to turn invisible. Wait till your foes get near and launch a sneak attack!
  • Rocket Crowbar - It’s a crowbar! With a rocket on the end! Swing it into players to send them flying, or use right click to fire drunken rockets at people. You can also hit the map itself to send yourself flying away for quick escapes.
  • Dubstep gun - One of the very first weapons added to the game way back in early 2012, this massive weapon plays dubstep music and essentially acts as an area of effect flame-thrower. Anyone subjected to this for too long will naturally have their head explode.

AND MUCH, MUCH MORE!
