- "TUFBREW! That's what I'm talkin' about!"
- — Tank Dempsey
Tufbrew is a cut Perk-a-Cola that was going to appear in Ascension. The only proof that it exists are in the character sound files with 'perk_tufbrew' in the name. Dempsey's quote is the only one that mentions the perk by name.
Nikolai mentions it "goes down like glue", suggesting it is thick, similar to the way he describes PhD Flopper. The "brew" ending suggests its a beer-based drink.
