Gladiator Arena by Clownz
In this map you control a gladiator (1-6 players) and fight through a series of boss battles, which require dodging and learning each boss's unique mechanics. When you defeat a boss, you gain new equipment and items to strengthen your gladiator, which saves from game to game so that the more you play, the stronger you get.

Hermoso mapa y la musica del video es tremenda
