I am rebranding the DLC from being a donation - to unlock 5 extra game modes for 5$.
-Zombie DLC has already been removed.
-Hat DLC will cost 5$, and unlocks all game modes.
-Bling DLC will cost 30$, and is only there for those who want to unlock all Steam trading cards (Not worth it, but those are Steams rules not mine).
This prices will change in about a week.
The five extra game modes (plus cards) will be released around Jan 2019, after the Xbox ONE release.
