ok so this is the map i call Grotto Collider. this map was inspired by a scientific research facility in Switzerland called the Large Hadron Collider. what this large machine does is separates the +&- neutrons from an atom and sends them in opposite directions accelerating them to near the speed of light then smashing them together. the purpose of this research is to recreate conditions that may have been one billionth of a secant into the big bang, and also to test Einstein's theory (E=MC2) to convert energy into matter.

so the story goes the Grotto Collider was built by the forerunners and discovered by humans deep in the earths lower mantle. this is were the forerunners discovered faster than light travel and the humans discovered the facility leading them to the same end.
the map layout is kinda barbell shaped. it runs east and west with 2 circular rooms on each end one with a red light and one with an orange light. they both have a grav-lift an the back side of the room leading from a bottom level to a top level. between these rooms is a long open strait room with 2 open levels. there are long lines of site through here to quickly find the action. there are also 4 side paths off the red room, 2 top paths and 2 bottom paths. off the orange room there are 2 side paths at the top that connect to the center. there are a few ramps in between to provide quick routs from the top floor to the bottom floor.
there are lots of DMRs and needle rifles with 2 needleres, a spiker, a plasma repeater, a magnum, assault rifle, plasma pistle. the power weapons are an energy sword, sniper rifle, and a rocket launcher. the re-spawn times on the power weapons are 2 minuets but the rocket launcher does not spawn for 2 minuets after the start of battle. the rocket launcher spawns in the center of the map, the sword spawns in the orange room and the sniper rifle in the red room.
