Technically by the definition of a roguelike, this is by far such a game.
But, i promise this, and i'll keep it short: try it and you'll drool. This game is simply a gem.

On short, it's a turn based hulk based game, with squads that get medals, scars, ranks throughout the mission WITH, yes this is the best part, PERMA DEATH.
(Also be sure to check the options before getting in game and choose your settings for gameplay, be sure to add rank affects shooting, meeles and CP, if it's your fancy.)
The game is punishing, and it's that sort of game that keeps making you come back to it.
Posted this here because although not part of the genre, many people will find themselves attuned to the game.
Enjoy!
And feedback is expected !
