Any FPS worth its bits has a rocket arena. Now Roblox does too!
Inspired by how fun it is to nuke the bridge to Santa's Winter Stronghold, I designed a level that is all about blowing up bridges. This map is all about Rocket combat. Every player gets a Multirocket, the Wall Builder, and Jet Boots! Knockouts and Wipeouts in this level will count towards your stats.

I made this fun little game in about 30 minutes, which I think shows how powerful Roblox Studio is when you know how to use it. Feel free to copy this map and customize it, I don't know how long I will keep it up as my place.
