Destructapalooza was an arena owned by Thugs-4-Less. It was located on the planet Kragg in the Zarkov Sector of the Polaris galaxy. Much like DreadZone, it was completely unregulated, and served to prepare recruits into hard hitting Thugs-4-Less enforcers.
Destructapalooza utilized all natural lava for their arena, as Thugs-4-Less cared about the environment.
Despite the fact that Destructapalooza was on an abandoned sector, apparently it had a commercial about it.
There were two rejected cups called the Azeril Cup and the Zero-G Cup where Ratchet would fight Thugs outside Planet Kragg's atmosphere, similar to the cage match of Going Commando.
Bursting Blekkos, Nethers, Thug Raiders, and the B1 Brawler were cut out the arena and/or game.
Thug Raiders had concept art, but were canned from the game. The Announcer said they train thug raiders by pumping iron and watching bad action films.
Thugs would have lines in the stands while watching Ratchet fight in the arena.
Bonus Crates would drop into the arena for a limited time to give Ratchet ammunition. However, they were cut from the game.
Bladebot's trillium blades were used to torture Kerchu warriors of Planet Jasindu. The Destructapalooza cleaned up the mess and turned them into hotdogs.
In the Zero-G Cup, Ratchet would grav leap on platforms while shooting at Thugs from the Nebulox 7. As a punishment for failing to kill Ratchet a few hours ago, they had to kill Ratchet, or else they wouldn't return to the planet.
