Welcome to the Arena, where high-ranking warriors are transformed into spineless mush. Abandoning every ounce of common sense and any trace of doubt, you lunge onto a stage of harrowing landscapes and veiled abysses. Your new environment rejects you with lava pits and atmospheric hazards as legions of foes surround you, testing the gut reaction that brought you here in the first place. Your new mantra: Fight or be finished.
Quake 3, is without a doubt, one of my favourite games.
This game is amazing. I can play it offline for hours and hours without getting bored. The bots are great, and quite challenging on higher difficulty settings. The weapons are well designed but the machinegun was really crappy. Making stuff for this game is really easy and makes the game even better.
There isn't really a storyline to the singleplayer campaign. But this isn't much of an annoyence. I found the maps to be very fun, especially Q3DM17. The character models, and misc items are also very good. The game is mostly balanced (with the excpetion of the BFG) which makes it fair.
Overall, a great game that everyone should at least try once.
