Maze of Gains 2.0: What Onchain Heroes Rebuilt, and What Its Playtest Showed

Onchain Heroes closed an eight-day playtest window for Maze of Gains 2.0 on July 9, reporting 399 players and 4,651 runs on a dungeon crawler it had rebuilt from the ground up a week earlier — a new battle system, a new leveling system, and a finite 9-floor maze — with up to 500 Arcade Keys on offer to top scorers and content creators, Onchain Heroes said.

What changed in MoG 2.0

Maze of Gains is a dungeon-crawler mode built inside the wider Onchain Heroes universe, the on-chain RPG behind onchainheroes on Abstract. On July 1, the team unveiled MoG 2.0 as "a ground-up evolution" of the roguelike, built around a new battle system, persistent upgrades, and a finite 9-floor maze, replacing the open-ended structure of the original mode.

EGamers.io's writeup fills in the mechanics: the redesigned combat system requires players to "learn enemy patterns, adding a layer of skill and strategy over pure chance," and pairs a "novel leveling mechanism" with the persistent upgrades Onchain Heroes said carry across a run, on top of new biomes, unique rooms, and items. Entry to the playtest required holding a Ringbearer NFT or an Expedition Pass, per the EGamers.io report, gating the new build to existing holders before any wider rollout.

The playtest, in numbers

Onchain Heroes ran the rebuild as a live test rather than a quiet patch. The same day as the reveal, it opened an incentivized playtest with a 250 Arcade Key prize pool for players, and separately launched a content bounty offering another 250 Arcade Keys split across 50 winners for creating content about the playtest. By July 4, the team was describing the incentivized playtest as live with 500 keys up for grabs — the combined size of both pools.

On July 8, with the window closing, Onchain Heroes reminded players the playtest ended in 24 hours, with the 500 Arcade Keys split between top leaderboard scores and content creators. It wrapped the playtest on July 9: 399 players, 4,651 runs, leaderboard rewards promised "within 24 hours."

What we don't know

Onchain Heroes said leaderboard and content-bounty rewards would go out within 24 hours of the July 9 wrap post. We found no follow-up confirming the Arcade Keys were actually distributed. Sources also describe the playtest as gated to Ringbearer NFT and Expedition Pass holders; none of the beats or the EGamers.io report say whether MoG 2.0 is now open to the wider Onchain Heroes player base or remains limited to that cohort.
