Cogito, ergo sum
From Unreal Wiki, The Unreal Engine Documentation Site
The No Redeemer mutator removes the Redeemer from the game. Nothing more, nothing less. It does exactly what it says on the tin.
 Methods Inherited From Mutator (UT)
- bool CheckReplacement (Actor (UT) Other, out byte bSuperRelevant)
- This function returns false whenever an actor of type WarheadLauncher (the redeemer pickup) is encountered removing it from the game.
For all other objects the function returns true to let other mutators or the GameInfo (UT) decide what to do with it.
