Hardcore

Hardcore is entered from the Hardcore elevators in the lobby. There are three Hardcore elevators beside ten survival elevators. Once you are in, the mode stays Hardcore. Consumables are disabled. A ready button replaces the mode vote, and the match starts when most players ready up. Hardcore pays a different reward currency from the other modes. The tower shop prices Brawler, Necromancer, Accelerator, Engineer, and Hacker in Gems at level 50.

Level 50, then use a Hardcore elevator. Party sizes are still solo, duo, trio, and quad.

Bring detection and economy you already understand. Do not expect consumables. Gem-per-hour videos are creator routes, not a listed reward.
