I have recently posted up 4 reviews of some nice mods out there for you to check out!
First off, we have a review of The Specialists Beta 2.0. Its a great mod to play online, and offline too thanks to the bot support included. Review Here
Secondly, we have a great Quake mod, Battle Mech. Its a great deathmatch romp, and its standalone, so everyone can give it a try! Review Here
Third, we have The Third Reich 1.2. The Third Reich won the first Mod of the Month award here at modDB, and since then, its become brillient. Review Here
And last, but not least, we have Neo Cario. Neo Cario pits you into the far future, with a variety of Mechs, Vechicles and Suits to help you attack and destory the opposing team. Review Here
They are all fantastic mods, and worth a decent look into.
