What I propose is a new coliseum mini game based on the game mode "gun game" from the legendary series Counterstrike.
For those of you who don't know, Gun Game is a game mode, where after each kill, your weapon switches to the next weapon in a lineup and you win by getting a kill with the last weapon.
For the SK version, there would be two modes, "specialist" and "general". In "specialist", you only use one class of weapon (gun, bomb, or sword) while general uses all 3 rotations lined up sword into gun into bomb. The weapon lineup would be the same every game
All weapons are heat 10 with no UVs. Armor and shields are neutral to all damages with neutral status resist.
NO lockdown classes
Arenas would be BN sized super-brawl esque arenas with random respawns and various spike traps and respawning blocks.
Death by environmental damage results in a demotion.
At the center of each map is a medium-slow heal pad to serve as the center of action
Always free for all.
The bomb one has the potential to be an uber failure. First, they are mostly for support, not main damage dealers unless there's a big crowd. And even then, 2 bombers would stare at each other without touching.
