(approx. $16USD) GAMER: As above, PLUS access to a digital download copy of the full game from the first available alpha onward, including the actual release version. Windows/Mac/Linux. Special early-adopter price!
(approx. $800USD) MASTER AND COMMANDER: Everything from the $200 tier PLUS I'll work with you to create a custom part of YOUR design that only you can use. Note that this will still need to be balanced for fairness – backers won't be getting super-weapons that obliterate the poor donationless plebs.
