Devinity Flood Server's #1 and #2

Search for them in Garry's Mod multiplayer servers. You basically get creative mode for a certain time, in that time you get access to item that float, and sink. They have differing levels of health, 50 - 1,000. You then use the gravity gun to manipulate the items, and then use a weld tool to fuse the pieces together. When the time is up, you must board your boat and watch the water levels rise. Then it's game on. You use guns, grenades and rockets to destroy your enemies boats. When you are in water, you are eating by piranhas and steadily lose health until 0. Winner is last team or man standing. At the end of each round you can elect to keep your boat for a small fee. You earn money by surviving and destroying other parts of boats. You use the money for guns or costumes for your character in the server. There are fun rounds in between such as Pirates (Everyone gets a cannon and you can board other peoples boats which doesn't normally happen in the regular game type) and Speed round (limited build time).

Come have fun with us! I will make a trailer for it soon for you guys.
