Turok: Rage Wars is Unreal Tournament gone very, very bad. It's an ugly, unenjoyable mess at every turn.
The weapons range from the useless, to the exotic, to the two or three that will always be used. The warhammer is the useless weapon you're stuck with when you run out of ammo, and that happens often. On the exotic side there are the emaciator, inflator and freezegun. The inflator makes opponents grow fat until they explode, the emaciator makes them grow thin and the freezegun... freezes. But they're actually useful about 5% of the time. The primary functions do very little (especially the freezegun), but the secondary functions are all pretty lethal. The only problem: each secondary shot takes up half of the weapon's ammo. As if it didn't run out fast enough. The assault rifle's automatic mode (its primary is practically a peashooter) runs out in seconds flat before you have to seek out another ammo box.
The ammo scattered around every map is grouped into vague categories, and applies to any weapon of its type: bullets, energy, or explosives. There are also special weapons that can only be found in certain maps. One of them, the claw, is the most useful thing in the game because it completely blocks off one of the small, generic corridors.
...And speaking of the level design, it's abysmal. Drab, grey corridors and rusty brown corridors, lifeless green corridors and a couple of rooms that Tron vomited on for variety. They're all very small, generic and awkward, and the N64's controller doesn't suit them. The game's own control system adds to the frustration, making the essential need to move around and aim a test in self-torture.
Rage Wars is a multiplayer game by design, but also allows the use of bots. The singleplayer "campaign" boils down to playing the game's maps against different bots, which unlocks additional player models/skins out of the 3 you start with. The AI is very stupid, but human opponents aren't much better, in part because of the controls and also because you move like a rock. But that's of little concern anyway because most fights happen when opponents stumble upon each other among the game's cramped corridors and blind fighting ensues.
So the weapons are unbalanced and cursed, the maps are dull and awkward and the gameplay is frustrating. The end result is an ugly, unenjoyable mess of a game that fails miserably at the one thing it attempted: fast and intense multiplayer matches.
