Circular water arena with back hallways, switches below water to close off areas for hiding, maybe. Slim ammo, some doesn't register. No rechargers. Looks like those switches might work when dealing with more than one opponent.
From the very beginning you will get the impression of what the title of this map suggests. A very large room that has sub-rooms in the middle of it. The sub rooms are very tight and I mean tight! Teleporters take you from one room to the next but be careful, there is a ring of lava that surrounds the rooms. Large and wide corridors wrap the whole thing.
A very large net level that is quite fast in spite of the sight of line areas. Some very tall and large arenas with maze like hallways that connect them. Some water pools and transporters come with this one. EMFH would be best, but this level is flat and very huge, so make sure you have 5 or more.
A pretty fun novelty type net map. This one gives you the weapons but not the ammo. The ammo is given to you when the aliens die....A strange but different type of map. Give it a try...
