Two different maps, basically the same level. 4 Man Carnage is a large net level designed for 4 players. IMO due to the shear size of this thing you will need more than 4. It is possible with 4 with 4 very tall pillars that have slow moving platforms to give you access to the top. The pillars are in a very tall and large room, (arena) with one small room off to the side. Ammo is light but it does regenerate at a fast rate. The second: A very good water based arena map. I will quote from the read me. "This map is for the gladiators out there. There's nowhere to hide, sight always available. Yellow life machine for the brave. Lots of ammo. Good movement and agility is necessary if you want to win. Good for two players, and crazy for any more. Unlike lots of my other maps, the only aliens here are a couple of Ticks."
