Difficulty Hard
Description Complete a mission on Normal difficulty or harder without receiving any damage.
Repeatable Yes

Perfect is a Steam Achievement that requires you to complete a mission on Normal difficulty or higher without taking any damage.



  • The name and picture for this Achievement is a reference to the Valve game Portal. One of GLaDOS's lines went as follows:
"Perfect. Now move quickly to the chamberlock."
  • The picture is also a reference to Portal's ubiquitous "cake", which may or may not be a lie.
