If you like bugs (especially Termites and Ants) then you'll love this.
Get this, it's a Half Life 2 mod where you play as two opposing Insect forces.
The forces species are based on the insect's caste systems.
The modeling is very well done and the game play is fun and challenging.

Think of it as like the Buggy version of Command and Conquer Renegade (multiplayer version). It works like an RTS where each bug has it's own purpose, i.e. building, fighting, scouting, etc.
Example:
For Termites, to gather resources to build bugs and base defenses, you must find a certain patch in the ground. Then you gotta build a mushroom on it (lol i know). After that, you need to lead a pheromone trail back to the queen so a NPC worker can start harvesting the plant.
To get better units, you need to build their race-specific research towers.
To get a better spawning range, you need to breed more queens.

Activity right now is kinda ok...not too much unfortunately...that's why i came here to ad this so I can have more friends to play with :D .

They have YouTube video Tutorials, and a very friendly Admin. :)

And, in the future, if my suggestion goes through, they will also implement species of Hornets and *suggested by me* Bees.

So go on down and support this Built-From-Scratch-Mod, if you have Half Life 2, I would recommend getting it.
