Colossus

Summary
Colossus is a Halo 2 multiplayer map. This map is most probably part of the Heretic Base and Gas Mine. It consists of four main parts. The first section is the long corridor in the middle of the map. Here you can find an Overshield. This long corridor acts a large gorge between the the red and blue sides of the map. Both sides along with the corridor in the middle lead to the fourth part of the map which is the ramp area. Here you can find a shotgun at the bottom of the ramp and a Beam Rifle at the top of the lift that propels you from the lower corridor to the upper part of the ramp area. This is a map famous for the very prominent and newb-like Newb Combo. A good trick is to collect all the plasma grenades you can, then hang in one of the two huge windows near the bottomless pits (where the gas canisters drop in to). Blast everyone who shows up. The gas canisters provide a high advantage, if you see a filled one and somebody standing near it, simply by firing at the canister it can explode and kill.

Tactics

 * 1) Colossus is a big map- but there isn't much breathing room. Snipers will sit on the opposite side of the course and pick you off, either with distance BR/Carbine or Sniper Rifles. Don't let this happen. Know the course, and know the paths that will block their fire, or at least let you get your shields up before dying.
 * 2) The walkway near the Gravity lift is a popular battle spot. Check around corners and prepare for the worst anytime you're near there, and make sure to watch your back/each others' backs.
 * 3) The mid-sized windows near each ramp to the aforementioned walkway can be jumped through, for suprise or quick maneuvering.
 * 4) On the previous note, expect grenades to be thrown through them, and do so yourself. If there's a blip on your radar, or if there's someone that just went up a ramp, don't hesitate to toss a grenade or two up through them - it could mean the difference between full shield and no shield.
 * 5) Sniper rifles are commonly on this map. Don't hesitate to grab them, as they're infinitely useful.
 * 6) use the explosive containers to your avantage, shoot them when enermys are close to them
