Absolutely outstanding turn-based tactical combat game. Fantastic 2D artwork although the 3D character models could be improved. I hesitate to call it an RPG as it's completely linear and you seem to be replaying simulations of the scenarios in the game. The concept of enemies dropping skills when defeated as if they were equipment is unusual, as is crafting skills from other skills. As well as characters you can create a roster of robots and tamed beasts level up and have their own set of skills.

Troubleshooter is not a perfect game. There are problems I could list with the story as it stands, or small issues in gameplay that largely live in the later game of the DLCs.
But those nitpicks pale in comparison to the passion and ambition dripping from every inch of it. A small studio decides to spend the better part of a decade on a project, one which in essence is a prologue for a somehow even larger planned story despite being well over 100 hours long, and it works.
Getting to the credits and seeing that the game had TWO programmers was an extreme shock. Seeing that the devs have a 400 page thread on Steam to take ideas and feedback they've been maintaining for 6 years was too. The fact that such a small team created such a deep and intricate TRPG is downright inspirational.
Every character is unique and fun to use. Every character has a ridiculous amount of customization. Many maps provide a challenge even on the normal difficulty. It's a massive pile of ideas and systems built up over years that should collapse under its own weight, but never does.
