Sidewinder

4-16 players, Supports vehicles

Summary
Sidewinder is a horseshoe-shaped multiplayer map in Halo: Combat Evolved.

The main feature of this map is the ice patches on the front of the horseshoe in between the bases that can cause any ground vehicle without treads or hover abilities to slide, making it hard to control the vehicle. On the outer edge of the map are two large cliffs that are connected with teleporters to each base. On the inner edge, there is a network of tunnels which lead to the opposing bases. Four powerups can be found in the lower section of the tunnel. There is a sniper rifle, shotgun, Health Pack, plasma pistol, M6D Pistol,and assault rifle inside each base.

Glitches
There is a glitch here that lets you get on top of the map.You'll need both types of grenades and a rocket launcher. You just need to take a Warthog up to the little tunnel on the top and then park it where the front is facing the wall then get on top of the Hogs gun, then quickly throw both types of grenades and fire a rocket.

- It is possible to jump through the barricade separating the two bases. Step 1: Park a warthog on your side of the base with the passenger's side facing the enemy base. Step 2: After capturing the flag or whatever you need to do at the enemy base, run into their tunnels toward the gate. If you parked close enough to the gate, you should jump through into the Warthog and be on your side. The reason you get into the passenger's seat is so that if an enemy jumps through, you can have your teammates kill him before he can drive through your base in the Warthog.

Techniques
A Defensive technique in CTF is to Park A Rocket Warthog inside your base behind the flag and Move into the Gunner Seat picking off any enemies that enter.
