The Masterplan (Steam key/Region free).

http://store.steampowered.com/app/313080/
The Masterplan is an award-winning tactical squad-based heist game set in 1970s. The 2D top-down view gives you a great overview of what´s happening at any given moment, allowing you to be a real criminal mastermind. Features hand-drawn 2D graphics and fun group control, granting you total control - at least until someone calls the cops and everything goes haywire.

During the game you´ll need to heist your way through 20 unique hand-crafted heists in a persisting career mode, manage your crew from heist to heist by hiring the right goons and by making sure they are properly equipped. A test of a true mastermind will be to execute the plan to perfection, keep the goons alive, and walk away with the maximum loot from each heist.

Depending on your preference, you can hit your targets loud, or in stealth, or a mix of both. Keep the civilians under control, knock them out, or leave no witnesses. It´s all up to you, just make sure you won´t be there when the cops arrive - or be ready for a brutal firefight.

If you are hungry for more content on top of the campaign, you can test your mettle in the 8 challenge maps, built by the development team, available through Steam Workshop. And with Steam Workshop support, players can also create their own heists!
