Update: The Ragnarok expansion for Crimson Company and the Collector's Box are live on Kickstarter, and the campaign will run for 22 days. The Collector's Box Standard pledge includes a copy of the base game, the Ragnarok expansion, and the Other Side expansion. The Deluxe edition adds metal coins, a game board, and 3 castle miniatures.
In the solo/co-op mode, you essentially play both sides, and make decisions both for yourself and for your 'opponent'.
Our preview post below was published on May 7.
Crimson Company is a 2 player card game about two noblemen dueling for control of three territories. Originally a competitive game, it later received solo and co-op rules. In the Kickstarter campaign planned for May 12, Crimson Company will get a new expansion (Ragnarok), a big box to fit all content, a board, and an app available to backers of the Deluxe edition.
In the competitive version of the game, players are bidding to acquire sellswords, merchants and monsters in order to build an army and defeat their opponent. Three castles are placed at the centre of the table, and purchased cards are placed below them to form lanes. When a lane has four cards, it scores, and the winner is the player who conquers two of the three castles.
The Ragnarok expansion brings in Norse gods to the 'market'. These come with the new 'passive' ability that activates when certain conditions are met, even during the opponent's turn.
I couldn't find any details on the solo and cooperative mode, other than this blurb: "in the solo and 2-player cooperative variants, you'll play cards on both sides of the lane and will have to find creative ways to use your enemies' abilities against themselves".
