Game Modes
There are a total of 5 different game modes in Nuclear Throne. IDNTG covers the mechanics of Normal mode as a whole, but this section will cover Dailies, Weeklies, Hardmode and Co-op. These modes are mechanically very similar and provide little to no new content, rather just different ways to play. This page will serve as an overview.
Dailies and Weeklies are modes only available on Steam versions, Switch and Playstation. These are challenge runs where everyone on the same version/platform share the same seed. Steam has an online tracking form called thronebutt, and there is a community scouting sheet that shares mutation builds for Steam & Switch.
Hardmode (WIP) is a much more difficult version of the game that is unlocked by looping twice in any other mode. It starts the player off in H1 1-1, which is very similar to L1 1-1 while much more difficult.
Co-op (WIP) is a mode that allows for local 2 player that are locked to the same screen, otherwise largely the same as normal. Nuclear Throne Together is a mod that allows up to 4 player local and online play, which will overlap heavily with this page.
Unlocks and achievements can be gained on ANY mode, not just normal. The exception to this is that golden weapons cannot be unlocked on weeklies, and unlocks have been known to be buggy on co-op.
There are two achievements tied to Hardmode (Way of the Chicken & Good Riddance), as well as one achievement tied to Dailies (Not Bad). Despite 'Not Bad' being an achievement on Xbox, it is currently unobtainable. There are no achievements exclusive to weeklies or co-op.
