Renegade isn't bad for Westwood's first - and last foray into the first person shooter genre.
The Renegade campaign is set around the same time as the original Command & Conquer. You take on the role of Global Defense Initiative (GDI) commando Havoc in his fight against the multi-national terrorist organization the Brotherhood of Nod which is led by the enigmatic Kane. The story, like in most C&C games, is hardly anything spectacular, but it's a solid and complete story (five second ending cinematic aside) that ties its decent levels together very well.
Renegade's gameplay is fairly generic. You perform mission objectives in each level while blasting away your enemies. Basically it's like every other shooter out there. The sad part is that the AI is mentally deficient. Actually, that's an understatement. Your enemies will just stand there and shoot at you, or charge straight at you while shooting at you. What makes the AI challenging isn't their intelligence, because there's no intelligence there; it's their large amount of numbers. There are times when you end up battling a dozen or so Nod soldiers equipped with different weapons all at once. Sniper rifles, regular machine guns, mini-guns, rocket launchers, flame throwers, Tiberium weapons, some weapons can hurt you very badly if you're not careful. Fortunately Renegade makes up for its lousy AI with some pretty good level design.
Renegade came out during a time where level design was going downhill, but Renegade managed to deliver a very diverse selection in missions for the player to embark on. There's small European towns, tropical islands, battleships, mansions, etc. Most of these levels are big, and no two look at all alike.
Where Renegade really shines is its unique multiplayer "C&C mode". The player gets to play as a soldier for either the GDI, or Brotherhood of Nod, and their objective is to fight with their allies to destroy the enemy base while protecting their own. As each factions Tiberium Harvester returns to the Refinery from the nearest Tiberium Field each player gets credits which they can use to purchase vehicles, or switch their class. It's a really fun game mode, but Renegade's mediocre net code can often make games laggy.
Renegade's graphics were okay for their time. They were very colorful, and the animations and character models were solid. Some of the weapon effects are odd, though.
The audio... well the voice acting is decent for the most part. The sound effects are fine. The music is mostly a collection of remixes of classic music from the original Command & Conquer which is not at all a bad thing.
Renegade is a great game for its level design and multiplayer, but it's definitely a flawed gem. Lousy enemy AI, a very arcadey feel, and other minor flaws prevent Renegade from going down in history as a milestone in FPS gaming.
