30XX

30XX entered early access in February 2021 and reached 1.0 in August 2023. Made by Batterystaple Games, it follows 20XX: you play Nina or Ace, robots in the mould of Mega Man X, dashing, jumping and shooting through ten stages whose layout, power-ups and boss order change every run. Defeated bosses give you their powers, augments stack into builds, and runs can be played alone or in local or online co-op. A level editor lets players build their own stages and campaigns.

Daily and Weekly Challenges arrived in June 2021. Each challenge has a fixed random seed, so all players see the same level order and the same items in each level, plus a Challenge Boon and a few Entropy conditions that change the rules, with permanent upgrades locked to a fixed set. You get points for destroyed enemies and beaten bosses, and bonuses for avoiding damage and for time left on the clock. The Daily can be played once: your score goes on the day's global leaderboard, and your time too if you finish. The Weekly resets on Wednesdays and can be replayed for a better score.

One attempt on a known seed makes the daily a test of play rather than luck. Solo and co-op Dailies have separate seeds and leaderboards, so you can play both on the same day. Version 1.3 in September 2024 added Eternal Challenges, 21 rulesets that used to turn up only as a daily or weekly flavour and can now be played at any time. The last patch, 1.4, came out in February 2026.

It suits players who already know the base game and want a fair shared run to measure themselves by.
