Mining For Profits!
Your choice of either the Glorious PC Gaming Master Race or the Glorious Mac Gaming Master Race version. Which race is more master? That's entirely up to your wallet! Both versions will be free of that nasty DRM rubbish.
Both PC and Mac editions of the Glorious Gaming Master Race branch. For the agnostic master race.
Participation in beta testing, your name in the credits as a tester, and the previous reward tier.
Try your hand at level design! Create a level to be featured in a crowdsourcing campaign, either to be included on launch or later as a free content update. Also includes previous reward tiers.
An exclusive boxed copy of the game - DVD case, printed sleeve, and an instruction manual that consists of more than an epilepsy warning. Just like the manuals of old, basically. Also includes previous reward tiers.
Fancy yourself a writer? With this reward tier, you will be able to write a spam email delivered to your in-game inbox in the crowdsourcing campaign. And if that's not incentive enough - I bet you hardly ever see a sentence with three in-'s in a row. Surely that's worth some cash? Also includes previous reward tiers.
