Update: Turris has relaunched on Kickstarter (they first launched the game back in February), and the campaign will run for 23 days. You may back for a standard copy of Turris, or go for the all-in that includes a 5th player expansion, metal tokens and the tower miniature.
In the solo mode, the player will compete against the Betrayers, a rival faction who sabotages your efforts to build the Tower (the rulebook is available on the campaign page).
Our preview post below was published on February 8.
Let me say right off the bat that there is no information on the solo mode of Turris yet. It may be revealed when the Kickstarter campaign launches on February 11. In the meantime, you can check out their Kickstarter preview.
Turris is a 1-4 player worker placement game set in a strange fantasy world. Players are leaders of exiled tribes, sending out scavengers to collect resources in order to build a tower. This tower is meant to act as defense against roaming Beasts who chase the scavengers and occasionally devour them.
In gameplay terms, on each turn you will be placing your scouts in various locations to collect ichor. Ichor is the substance that powers everything in the game: you have to spend it to bring the scouts back, move them or resurrect them. Your main goal is to gather Prestige points, appointed by the Council that controls the tribes. In building the tower, you will seek to acquire Tarot (Trionfi) cards. These show the rooms that should be built and give the player extra points. Trionfi cards are gained when you complete the missions assigned to you by the Council.
The game comes with miniatures for the Beasts and scouts, and the central Tower mini (first player marker) is one of the stretch goals.
