One of the central events of Warhammer 40k history is the scrap between Our Immortal God-Emperor (We Praise His Eternal Vigil) and his lad Horus, who fell in with a bad spacecrowd. After years of slagging off his spaceda, Horus gave him a spacekicking and put him in spacehospital but got put down himself. Spacechristmas was forever ruined. All of that (well, some of it) is recreated in Talisman: The Horus Heresy, a spin-off from the digitised board game Talisman. You can relive that history for yourself this weekend, as the full game is free to try on Steam.
The Horus Heresy is a digital board game for 1-4 players, who take control of loyalist or traitor forces to duke it out in competitive or cooperative play. They quest, battle, collect gear, and generally power up in preparation for the final battle.
Here's a trailer to explain the basics:
I've not had a crack myself but have heard some good things about Talisman (and some not so good, to be fair). And let's not forget that one of RPS's core responsibilities is to provide familiar Warhammer lingo and lore to people who now worry they're too old to go into Warhammer shops.
You've got three days to hit Steam and download Talisman: The Horus Heresy. If you like it and want it for keepsies, hey, a 50% discount brings it down to £5.49/7,49€/$7.99 until Thursday.
