Serellen has had a rough go at trying to revive the CQB (Close-Quarters Combat) tactical shooter genre. After announcing, kickstarting and releasing Takedown: Red Sabre in late 2013, it was met with a lot of disappointment. Then in late 2015 the team announced a new take on the genre, a game called Epsilon that was released on Steam Early access.

If you ever played the original Rainbow Six titles (the PC ones from the 90s) - you know the best part about them was the planning phase. It was here you'd pick your team, equip them with gear, and then plan out a strategy that included routes, timing, and takedowns from a little top down tactical map. You could even run these plays without directly controlling your squad to see how well your plan would work. The recent indie game Door Kickers captured this feeling, but it missed the option to go in direct control.
