This is a tutorial of how to get into the Blue Room Under Snowbound. 1. Overload the map by spawning 4 trip mines and setting the minimum respawn time to 4 and keep using them until the first one runs out of time and blows up.
2.Go to the base with a room under the floor.
3.Get a friend there too. Spawn a a human or covenant turret and make him go on it.
4.Than lift up the turret with him in it and turn it side ways and move it down and make the friend go into oracle mode. Congrats you are under the blue room. You can also put respawn points under it
