There are a total of 44 different achievements in Nuclear Throne which covers a wide arrange of progressions and unlocks, as well as finding some secrets.

Add links to survival guide, characters and areas later.

These are 5 achievements in the game that are particularly difficult or enough on the technical side to warrant guides, they are as follows:

• - Everything Hurts
• - Unstoppable
• - Frog Zone
• - Good Riddance
• - Ultra Mutant (100% unlocks)

Notes for achievement unlocks:

• "Reach the Nuclear Throne" refers to actually sitting on the Nuclear Throne, rather than just starting the fight.
• Steam version: achievements were only added at official release, so there may be inconsistent percentages between unlock and progression achievements.
• Xbox version: the "Not Bad" achievment is currently unobtainable without daily challenges. Vlambeer is aware of the issue.
• Playstation version: includes all the same achievements(trophies) but also includes a 45th - "It's Not Fair, It's Not Right" for completing every other challenge.
