only 4 tweaked abilities, it'd be a gamemode like replication or escalation, maybe in a swiftplay format
everyone can buy a:
kayo flash
raze nade (1 explosion)
brim molly (smaller radius, shorter duration)
viper orb (no fuel needed, one time use and no decay, make it a bit smaller and the duration shorter)
all util would be expensive so it doesnt become sit and wait behind a choke simulator
