Comptonβs Cookoff Half-A-Minds count as Psychonauts 2 collectibles youβll have to find in the fourth brain Raz gets to explore. Comptonβs Cookoff is the area accessed immediately after Hollisβ Hot Streak. There are two Comptonβs Cookoff Half-A-Mind collectibles youβll have to find here if you aim for 100% completion at the end of the video game developed by Double Fine Productions.
When you start this level, youβll notice that your goal is to win a cooking contest. Since youβll be racing against time, focus on finishing all three cooking rounds, totally ignoring the collectibles in this area. The time is also not important, meaning you can also finish the level if the time runs out.Β Then, replay the level using the device in Sashaβs Laboratory and mop up all collectibles.
Half-A-Mind #1 & 2
Brain Location: Main Stage
Normally, both Comptonβs Cookoff Half-A-Minds must be won by completing two out of three cooking rounds within the allotted time. If I am not mistaken, the first two, however, may not be possible for some players.
Therefore, youβll find both Half-A-Minds simply by replaying the level.Β As you can see below, they are outside the Mystery Boxes that vanish after defeating the judges at the end of this level.

So, simply put, to get these two, just finish Comptonβs Cookoff Brain, then replay it. The collectibles will wait for you near the stage.Β
