Lethal Stigma is a multiplayer role-playing first-person shooter for the Source engine.
Taking place in the Half-Life 2 universe, LS immerses the player in a familiar world with six exciting gamemodes and a boatload of unique features.


Team Elimination
In TE, players are spawned as either a member of the Resistance or the Combine. They are then encouraged to dispose of members of the opposing faction in a timely manner. TE is not to be confused with Team Deathmatch, because should a player die, they will respawn on the other team. The game continues until all players on one side are killed and an entire force is eliminated, at which time the opposing faction wins.

Free for All
Similar to HL2DM's Deathmatch gamemode, FFA is frighteningly fast-paced and chaotic. The objective is simple: kill or be killed; to win, you must kill the most enemies. What makes this gamemode far more fun and addicting than a simple game of Deathmatch is Lethal Stigma's many unique features and class system.

Capture the Flag
Lethal Stigma's take on CTF is a unique one. Rather than having two team-based flags, there is a single flag hidden somewhere on the map that both teams are encouraged to locate and capture. Once a flag is captured by either a member of the Resistance or the Combine, that player becomes a flag carrier who is unable to use any weaponry. Therefore, the carrier must rely solely on upgrades and the help of his teammates to survive for a given period of time. Once enough time has elapsed and if he is still alive, the flag carrier’s team scores a capture point and another flag is spawned and hidden. The force who obtains a certain amount of capture points before the other team is declared the winner.

In tribute to Agent Red Production's other project, Situation Outbreak, this gamemode pitches players against the undead. Get your friends and duke it out against mass numbers of zombie and headcrab NPCs. The one who kills the most creeps before time runs out will be declared the winner.

[Coming Soon] Extermination
Choose a side, your abilities, and a class, and work together with your teammates to eliminate the opposing team, and survive an endless onslaught of the zombie horde! A more strategic, team-dependent gamemode that ignites a three-way war on the battlefield! No more going rogue, no more being John Rambo, and no more spawning!

[Coming Soon] Attack/Defend
The two teams are pitted against eachother in a brutal Attack and Defend style gamemode. One team is tasked as the defenders, who take control of heavily-fortified areas and hold off against the attack team, who must deliver a bomb and fulfill specific objectives to get closer to the bomb target. If the defending team holds off until the timer stops, they gain a point. Then the teams switch. A hectic, and also very strategic gamemode is making its way to Lethal Stigma!


TANK - Armed with an AR2, this beast has double the amount of health as his counterparts and plenty of firepower, making him the perfect bodyguard. However, this strength comes at a price: he's quite slow. That being said, the tank is a class that thrives in indoor and outdoor environments alike, so if you like brute force, you're in heaven.

ASSAULT - A good balance between speed and power, the assault class moves quickly and wields a sub-machine gun. It is deadly in numbers and popular among players new to the game, so you had better watch out before making your way into an enemy base.

SNIPER - Needless to say, the sniper is excellent at killing enemies at a distance. Armed with a scary-accurate crossbow, this class is a perfect choice for players who like to think tactically and plan out their attacks. Just make sure you avoid any close encounters with the enemy.

ENGINEER - Need a dispenser here! Armed with balls of steel, the engineer class is the only class that can manipulate its surroundings with the powerful gravity gun and support his teammates on-demand with automated floor turrets. Wielding Alyx's gun from the HL2 series, he is an excellent choice for those who are already familiar with games like HL2DM and TF2.

MEDIC - Charge me doctor! Okay, I'm done with the TF2 references, I swear. Lethal Stigma's medic is equipped with a powerful shotgun to make up for his low health. He is also provided with a single health kit. Heal your teammates and be rewarded, or be a selfish bastard and heal yourself. The choice is yours and yours alone, my friends.


  • A sophisticated experience system that rewards players for achievements such as grenade and melee kills, killing sprees, kill assists, and much more.
  • The ability to upgrade your character using recyclable upgrade points to increase your effectiveness on the field of battle with special abilities (invisibility, health regeneration, armor-piercing rounds, etc) and powerful weaponry.
  • A unique accuracy system that encourages tactical assaults over firing blindly at an enemy.
  • Access to both classic HL2 and brand-new weapons and items such as dual pistols, Alyx's gun, portable health kits, and deployable turrets.
  • Colored player models, to tell apart the Resistance players from the Combine players
The latest version of Lethal Stigma is v0.1.2, a public beta release. v0.1.3 is currently in development.

After five glorious years of developing modifications for the Source engine, the last year of which we’ve been largely inactive, it is with a heavy heart I announce the official closing of Agent Red Productions. Work on all projects, new and old, have ceased indefinitely. Our website will still be up for a couple more months until the domain name expires, but with limited to no support.

I hope this hasn’t come as a shock to anyone. That said, I do apologize that we were not able to finish the projects we set out to complete. Ever since Lethal Stigma’s development team all but disappeared and Half-Life 2: Retaliation’s development came to a close following an unfortunate data loss incident, our studio has had little to no in-house support, only retaining a core few active members along the way. It has always been my intention to complete development on Situation Outbreak 2, and I believe there’s still plenty of room for improvement with Contingency, but we simply do not have the resources to see those projects through at this time, nor have we for the past year. Perhaps one day they’ll see the light, but in the meantime, we cannot continue.

I want to personally thank everyone involved in the development of all of our mods throughout the years, regardless of contribution or commitment. We could not have gotten as far as we did without you. I would also like to thank everyone who has supported us and played what we’ve produced, especially those who have been with us since our inception. Our projects were always made for you, the community, and so we sincerely hope you’ve enjoyed them.

If you have any final comments, questions, suggestions or concerns for any of us here at Agent Red Productions, please email me at james@agentredproductions.com and I will get back to you as soon as possible.

Lethal Stigma's bots are incredibly stupid as they were only implemented and ever supposed to be used for testing purposes (i.e. they will not actually play the game). That said, you can still add them and play around with them if you'd like by enabling cheats via your console (sv_cheats 1), then spawning them using the 'add bot' command (bot_add) -- I think.

Everything is good, models, guns, but the only thing bad is that no one plays on it!
