STALZONE lays out the Coliseum Rating rules ahead of the season

EXBO published a set of cards on Steam explaining how Coliseum Rating works in the PvP mode that arrived on July 22. The announcement gives no start date for the season.
EXBO has published a set of info cards on Steam explaining how Coliseum Rating works, the competitive layer STALZONE's PvP mode still lacks. The studio asks players to study them before the season starts; the post doesn't say when that is.
Coliseum landed on July 22 as endgame content: four teams of three players, no PvE at all, and no entry until Bar level 3. So far it has been played without a ladder, and that is what the season is meant to change.
In between, the studio has been correcting the mode. The July 29 patch raised the full-squad wipe penalty from 10% to 15%, cut explosive barrel damage from 310 to 250, and merged solo players and groups of up to three into a single queue on the NA, SEA and NEA servers.
The August 5 patch reworked the payout: reputation and battle tokens now depend on how the match ended for your team, and the winning side's bonus went from 10% to 25%. It also added a nine-challenge chapter to the Event Hub and made each Season Pass task count double.
The fine print of the scoring lives in those cards. The start date does not: it still has not been announced.
