I have put together a ranked list of what I consider to be the best free mods currently out – no waiting, you can play these free right now.  Feel free to comment if I missed a good one, or disagree with their rankings. Each of these mods requires that you have Steam installed in order to play (some also require that you own a Source title – list of source titles).

Alien Swarm

Alien Swarm is one of the best multi-player titles to come out this year.  It sports a unique top-down interface (it’s possibly to play it FPS if you prefer). One can easily put 40 hours into the game playing through each of the different classes, achievements, and difficulty levels.  What really set this mod apart is that it was released free of charge.  One does not even need to own another Source game (unlike most of the other mods in this list).  This game is an easy choice for the top spot. It also has by far, the largest number of active gamers at any one time of all the mods.

Zombie Panic! is an awesome amazing astounding mod that allows a large group of players to engage in a large scale multi player team battle.  Every match at least one player spawns as a primary Zombie, and the rest as a group of scattered survivors.  The survivors must do everything they can to barricade themselves and work together to hold off the ever growing Zombie swarm.  Each survivor that dies or is bitten respawns as a Zombie. The developers have announced their intentions to release a sequel call Contagion.  The game is hugely popular, and has several hundred players playing it at any given time.

Insurgency is an extremely realistic CS-style online FPS that pits insurgents against the US military.  Strong squad tactics, and one hit kills may leave those used to Counter Strike frustrated, but after playing a few rounds the game really starts to draw the player into it’s realistic battle environment. The game has a fairly strong multiplayer community, with a steady group of populated servers always available.

This game is ridiculous.  It’s also ridiculously fun.  You choose from three  different player teams to be either a Pirate, a Knight, or – yes you guessed it, a Viking.  You’re probably wondering if that screenshot really shows a Pirate flying through the air with the exploded remains of his Parrot floating over a red bearded Viking.  The answer is yes, and so yes, you should go download this multiplayer deathmatch and enjoy.  It’s rough, but it’s fun and there’s usually almost as many playing this as Insurgency (This is the mod everyone goes to when they get frustrated by Insurgency’s difficulty.

Mini Review:

The game is fast paced, and purely multiplayer.  If you’re looking for an FPS online deathmatch with solid controls, this game will fit the bill.

One unfortunate thing to note – the free version of the game does not qualify for free access to mods, so you’ll still need to purchase a Source engine game in order to play popular mods like Zombie Panic.

Important Stuff:

Extras:

You will also receive some other games free depending on your video card.  Also, there’s the HL2 Deathmatch University that host these map packs.

The game is visually beautiful, and fun to explore – don’t expect too much as far as gameplay goes – the entire thing can be finished in under ten minutes even if you go at a snail’s pace.

Longer Description:

Half-Life 2: Lost Coast is a small additional level for the 2004 first-person shooter video game Half-Life 2. Developed by Valve Software, it was released on October 27, 2005, through the Steam content delivery service as a free download to owners of the Microsoft Windows version of Half-Life 2. Lost Coast serves as a technology demonstration, specifically showcasing the high dynamic range rendering implemented in the Source engine. The level was designed with a variety of appropriate environments to emphasize these effects. In addition, Lost Coast was the first video game developed by Valve to allow developers to explain various elements of design as the player progresses through the level.Lost Coast follows Half-Life protagonist Gordon Freeman as he travels up a coastal cliff to destroy a Combine artillery launcher in a monastery, which is firing on a nearby town. The Lost Coast level was originally created for Half-Life 2, but was ultimately removed from the game. As a result, it has several minor story details that were not included in Half-Life 2. The level received a generally positive reception, and there was consensus among reviewers that the new features included in Lost Coast should be integrated into future games released by Valve.

Mini Review:

Gang Garrison is an impressive clone for a number of reasons; it does an excellent job of spoofing the startup screens, showing an authentic looking steam login, only naming itself Smoke instead of steam as the game boots.  There’s even a hilarious jab at Valve’s logo that one must see to believe.

But most impressive of all, beneath the spoof is a fully functional and very fun multiplayer game.  Considering the small size (under 16 MB), and the 15 seconds needed to boot the game and join a populated multi player server, this is a must have for anyone looking for multiplayer gaming on an older machine, or those that always dreamed of being able to double jump in a side scroller (that would have made Mario a lot easier!).

All 9 classes are there, and they’re all pretty fun to play.

Classic Map Pack

Longer Description:

Gang Garrison 2 presents the player with 9 unique classes to use in frenetic, cooperative multiplayer action in a stylish and unique 8-bit style. Battle with your friends or others you encounter online through a whole range of vibrant maps; TF2 maps reimagined in 2D as well as a multitude of maps with all sorts of different looks and settings, all of which have been dreamed up and constructed by members of our community. We’ve made a huge effort to provide simple, bugfree custom map support, so that anyone with a paint application can put together a map and test it themselves with our Garrison Builder utility. We also gladly encourage Gang Garrison modifications; many successful mods have been incorporated into the game as new features.

While this game has come a long way, it is still a work in progress and many impressive new features are being planned such as new gametypes and alternate weapons. Because this game continues to grow only because of the devotion and hard work of our community, we invite you to come and participate in the future of this game. We are always looking for talented people to join the forum, contribute art, content, ideas, and modifications, and maybe even help us behind the scenes on new official versions. We hope you’ll stop by and have a look at our game; it is the imagination and spirit of our players that makes it so fun.
