Here is Mantis Arena by MorsLupus. It’s actually called Mantis Arena 2 but I’m not planning on uploading the other versions so I’ll just call it Mantis Arena. You can play this with Slayer, Strongholds, or Breakout. I prefer Breakout for this map. You must eliminate the enemy Mantises in this city like map. There are 5 doors that you can shoot open and there’s a train that runs through the map every so often. You can use the Man Cannons to get on top of the buildings. It’s a ton of fun with a full lobby so give it a download.
