Indie roguelike Shotgun King takes chess and adds hot lead and a grudge

pcgamer.com:

Shotgun King seems deceptively simple and silly on the surface: take the king from the so-called game of kings and replace his armies with a boomstick. The funny premise belies a supremely addictive turn-based roguelike, one of the best to come around in a while.

The chessboard's black king has managed to alienate every piece in his army, driving them to switch sides. With no other option, he picks up a Royal Shotgun and swears bloody revenge on the white king and his turncoat subjects.

Every stage features a chess board with increasingly difficult layouts of enemy pieces for the king to navigate, with an end goal of, what else, eliminating the opposing king. The player's king can move one space in every direction each turn or take aim with his trusty shotgun. The shotgun follows typical videogame rules, being most effective close-up but having a spread on distant shots which allows you to clip multiple enemies with less damage.

At the end of each stage, you're provided a choice between two mutually exclusive upgrades, each one strengthening the king and the opposing team in different ways. You might choose between a valuable +2 range boost paired with a modifier that strengthens enemy pawns, vs. a flat damage boost attached to a modifier that spawns additional rooks, for example.

It feels strange comparing this adaptation of chess to other videogames, but the action reminds me most of Subset's Into the Breach or Firaxis' new XCOM games. Shotgun King has that same sort of oh shit moment when you've realized you've backed yourself into a corner, the AI's about to wipe out a successful run, and you know you have no one to blame but yourself. The traditional pieces of the game of chess lend the game a healthy enemy variety
