Halo: Combat Evolved/Gephyrophobia

There are no scorpions available on this map.

Snipers
The first thing you should know is that the middle spire is glitchable: you can reach it without a banshee. When there's a sniper up there, there isn't much you can do. An experienced glitcher and sniper knows you must check all the main sniper positions for enemies. The element of surprise is mandatory to win a match relatively easily.

You will need a lot of flying men to take him out if he is using explosive weapons. When in a banshee, don't get too close, even if you have infinite grenades – so will he. He will stick a plasma grenade to your banshee and it will most definitely kill you, or at least take off your shields and damage you badly.
