Top 10 Legendary Game Mods That Made Waves Throughout History

In recent years, Black Mesa has garnered significant attention and a large, vocal community has developed around it. Black Mesa is the award-winning fan-made recreation of Gordon Freeman's groundbreaking journey through the Black Mesa Research Facility. Originally developed by a group of passionate developers, this remake of the original Half-Life, fully endorsed by Valve, has evolved into something more ambitious.

With the help of the Steam Early Access platform, the team found the resources to remake and overhaul the controversial Xen chapters of the original, making them more in line with the quality of the rest of the game. The original game's 'Xen' chapters, actually five chapters: Xen, Gonarch's Lair, Interloper, Nihilanth, and Endgame have all been remade and expanded upon, and some sections that Valve had to cut have been reintroduced in Black Mesa.

When Valve created Xen, technical and time constraints affected the interface. Black Mesa redoes existing levels, creating games 'deceptively simple on the outside but complex within.' Some areas, especially the dam in Surface Tension, have been greatly expanded, providing a much more impressive feel than the original. Players automatically crouch when they jump, giving Black Mesa a more modern feel. Sound is another area where Black Mesa excels, with professional-grade sound, music, and voice acting. The voices, especially those of scientists and security guards, closely resemble those in the original game in an impressive way.

Half-Life birthed some magnificent mods, and quite a few of them evolved into standalone games. Garry's Mod is one such example, although its name still retains the 'mod'. Garry's Mod encompasses the ability to modify games by developing scripts written in the Lua programming language. The basic gameplay mode of Garry's Mod lacks fixed objectives, providing players with a sandbox world to freely manipulate objects. Other game modes, notably Trouble in Terrorist Town and Prop Hunt, were created by different developers as mods and installed separately, such as through the Steam Workshop. Players can spawn non-player characters, ragdolls, and props as well as interact with them in various ways.

Garry's Mod was created by Garry Newman as a mod for the Valve Source Game Engine and was released in December 2004, before being expanded into a standalone release published by Valve in November 2006. Ports of the original Windows version for Mac OS X and Linux were released in September 2010 and June 2013 respectively. As of September 2021, Garry's Mod has sold over 20 million copies. Players can spawn non-player characters, ragdolls, and props as well as interact with them in various ways.

Galactic Warfare is a complete conversion mod for Call of Duty 4: Modern Warfare created by Black Monkeys, recreating the multiplayer mode of the famous military shooter with characters, weapons, and locations from the Star Wars universe. The authors provided numerous battlefields, characters, and iconic weapons from Star Wars with the excellent gameplay of COD4-Multiplayer. You can play as a rebel soldier or an Imperial trooper, team up with some friends, and experience various weapon types, sightseeing spots in the Star Wars universe.

When this mod was released, there wasn't much news related to Star Wars games. Star Wars: Galactic Warfare maintains the gameplay from Call of Duty 4: Modern Warfare, however, completely changes the appearance of the maps, weapons, and characters. Sound effects are also altered to fit the weapons used. Every detail, from character models to sound effects, is so realistic that it surprises viewers. Weapons not found in the series, including bows, Imperial rifles, and even Tusken Raiders' rifles, function like rebel sniper rifles. The mod Star Wars: Galactic Warfare is an impressive achievement in terms of aesthetics and attention to every little detail.

PlayerUnknown, the alias of Brendan Greene, created one of the most influential Battle Royale mods ever made. It originated as a mod based on another mod, DayZ, removing zombies and adding weapons across the map for players to scavenge. These ideas bear a striking resemblance and are likely inspired by the Battle Royale manga. Brendan Greene later updated this mod for Arma 3, evolving into a creative developer for Bluehole, ultimately realizing his vision with PlayerUnknown's Battlegrounds. The game would go on to become one of the top 15 best-selling PlayStation games of all time.

PlayerUnknown's Battle Royale is a harsh survival mod plunging players into a blood-drenched last-man-standing game mode, with a chance to emerge victorious. Based on the book/film 'Battle Royale,' this mod delivers a unique gaming experience. The rules are simple; only one can win. PlayerUnknown's Battle Royale mod pits dozens of players against each other on Arma 3's sprawling maps. Players start with no gear and must scavenge simultaneously while keeping an eye out for other players and the shrinking play area, which consistently shrinks to increase conflict. PlayerUnknown's Battle Royale, the ARMA 3 mod that served as the starting point for the acclaimed indie game PlayerUnknown's Battlegrounds, has been inducted into the Mod Hall of Fame.

Team Fortress Classic, also known as Team Fortress 1.5, stands as a game within the Team Fortress series. It's an online multiplayer first-person shooter developed by Valve and published by Sierra Studios. A port of the Team Fortress mod for Quake/QuakeWorld, Team Fortress Classic was originally released for Windows on April 1, 1999, as a mod for Half-Life and based on the Half-Life Engine (GoldSource Engine). The development of Team Fortress Classic was led by John Cook and Robin Walker, two of the three designers of Team Fortress.

The game itself includes multiple teams, each with access to ten classes, competing in various modes like Capture the Flag, Control Point, and Escort. This Quake mod had such a significant impact that it almost single-handedly birthed a subgenre of first-person shooters known as Hero Shooters today. Team Fortress Classic became so popular that Valve acquired the rights, leading to the creation of Team Fortress 2. Team Fortress 2 stands as one of Valve's greatest treasures. Fair to say, its design and gameplay have heavily influenced the emergence of famous Hero Shooter games like Overwatch. As of 2003, the game was one of the ten most-played Half-Life mods according to GameSpy.

The Dark Mod began as a modification of Doom 3 in 2009, and later it evolved into its own version. The mod was originally aimed at revamping the gameplay of the original Doom 3. Eventually, it grew into a spiritual successor as it became a standalone game. It provides the framework and basic tools (tools, content, models, and editor) for over 160 fan-made missions, including several multi-mission campaigns. This open-source mod has turned Doom 3 into a modern reboot of the stealth genre that stealth genre enthusiasts have been eagerly awaiting, but Square Enix refused to provide until Thief 2014.

The Dark Mod is a first-person stealth video game that is free and open-source, inspired by the Thief series of Look Glass Studios. The Dark Mod is set in a classic gothic-inspired science-fiction world. Dozens of fan-made missions and campaigns have been introduced to the mod, and since 2013, you don't even need Doom 3 to play them anymore, as Dark Mod 2.0 has been released as a standalone game, much more appealing. Players take on the role of a nimble thief in a hostile world, having to use their wits and environment to evade guards, traps, creatures, or other threats. The best thing about The Dark Mod now is that it's a completely free first-person stealth game, showing respect and acting as a homage to Thief, yet it also manages to become something of its own.

Prior to the blazing success of League of Legends and Dota 2 alongside multi-million-dollar esports tournaments, there existed the Defense of the Ancients mod for Blizzard's legendary strategy game Warcraft III: Reign of Chaos. The origins of the MOBA genre are clearly depicted in Defense of the Ancients. The mod features heroes that you can level up, AI assistant armies, and the objective to destroy the opposing team's Ancient. Valve secured the rights to Dota and followed up with the highly successful Dota 2, but if you still want to play the original mod, you can find it on Moddb under the name DotA Allstars.

This is another mod that birthed an entire genre of gaming. Defense of the Ancients may not be the first MOBA mod or Multiplayer Online Battle Arena ever created, but it's certainly the most famous mod. Originally a Warcraft 3 mod, Defense of the Ancients became so popular that it could compete with the game that birthed it. This game alone is responsible for the existence of titles like League of Legends, DOTA 2, and all the other multiplayer online games that came after the original DOTA.

Originally a Quake mod, Killing Floor was just a game about killing zombies and dealing with increasingly difficult waves of zombies. It served as the precursor to zombie modes and mods for other games. This mod had such a significant impact that it inspired the existence of first-person survival shooter games that we still see today. It's very likely that games like Left 4 Dead became a reality thanks to this mod.

The mod version of Killing Floor is no walk in the park for those accustomed to the retail version of KF. The gameplay is similar to the retail game of KF, however, the mod version of Killing Floor has some differences that might catch newcomers off guard, such as a more complex HUD, annoying Med-Syringe, strange enemy animations, tougher enemies, and grittier weapons and levels. The music samples are also more diverse compared to retail KF. Each player has a unique, albeit different experience even though they use the same basic soldier body. This mod eventually evolved into a fully-fledged game known as Killing Floor. Eventually, the gaming world also got the fantastic Killing Floor 2.

Street Fighter 2 remains one of the most popular fighting games of all time. It has pushed commercial licensing to an unprecedented level of popularity. Despite its numbered sequels and various spin-offs, Street Fighter 2 continues to sell well and be played frequently. However, the game might have been forgotten if it weren't for a mod. Street Fighter 2: Rainbow Edition adds numerous features to the gameplay of Street Fighter II: Champion Edition not found in the official game, including Ryu and Ken being able to rapidly perform their special Hadouken move five times in a row, Guile's Sonic Boom being able to hit opponents, and various special aerial maneuvers. Players can also press the start button to switch their character mid-match.

Street Fighter 2: Rainbow Edition is a faster-paced version of the original game. Despite claims by many Street Fighter fans that these alterations to gameplay replaced all skill related to luck and button mashing, the game proved to be a favorite. Despite its imbalance, people enjoyed playing it simply because it was new, different, and faster. Ultimately, it inspired newer, faster versions of Street Fighter 2 with new characters and moves. This is especially notable because Capcom often attaches some legendary events to character moves.

This is another game that only veteran gamers know the origin of. Counter-Strike originally started as a Half-Life mod. Originally designed by Jess Cliffe and Minh 'Gooseman' Le, the mod's success was so immense that many who played Counter-Strike didn't even realize it was a mod. Eventually, Valve acquired intellectual property rights to the game mod. Later, Valve decided to turn Counter-Strike into a full-fledged product released in 2000.

The game remains popular to this day and is one of the most influential first-person shooter games ever to exist. In Counter-Strike, terrorist groups battle to carry out actions like bombing, hostage-taking, and assassination while counter-terrorists try to stop bomb defusals, rescue hostages, escort missions. Two teams of five compete in a standard competitive match. Players must buy armor, weapons, defusal kits, or rescue gear, while managing each team's economy in their game to maximize their chances of success. The first team to win 16 rounds in Bomb Defusal or Hostage Rescue mode wins the match.
