Gamers vs Hellfire

I had never actually heard of Rapture, an SF game about the titular Biblical event happening on Earth after humanity colonises space, but the Gamers vs Hellfire bundle is $50 of stuff for it for $10, going to support the victims and fire-fighters of the Australian bushfires. I know people who had to evacuate their house because of the fires, so I bought this bundle sight-unseen. Rapture looks interesting, which is a bonus.
