Set in an alternate version of WWII, Broken Lines from developer PortaPlay and Super.com is a story-driven tactical RPG and it's out with Linux support.
A squad of soldiers crash land in the middle of enemy territory. With no leaders alive and no available orders, the group must find a way to deal with their situation and internal conflicts, before a mysterious fog engulfs them and enemy forces hunt them down. Broken Lines is a game about a group of soldiers under immense pressure, losing hope and directions, while still trying to put up a fight.
I've not personally had long with it, as the publisher sent over a key last night. However, the first impression is good—really good. Early Steam user reviews are quite positive about it too. As a massive fan of turn-based strategy games, especially anything XCOM-like, I've been quite engrossed in it. The way you plan out the route for each soldier, then hit play and watch it all unfold (known usually as "WEGO") is a really fun mix. I'll be playing it through and providing more thoughts in due time.
