The Technomancer is a sci-fi action-RPG set on Mars. You start as a technomancer from totalitarian corporation/city-state called Abundance.

The avatar is pre-set (always Zachariah Mancer/Rogue) with customizable appearance. There are 4 combat skill trees: rogue, warrior (staff), guardian and technomancer (electro-mage); and 6 non-combat ones: charisma, science, lockpicking, stealth, exploration and crafting. Some are more useful, than the others.

Combat is challenging and enjoyable - you can get surrounded and killed in 3 seconds, if you don't pay attention. The opposite is possible as well, you can win, if you know your, your companions' and enemies' strengths and weaknesses. Animation cancel is presented. Enemies are diverse and require different tactics. Locations are semi-open (medium/large areas connected by loading screens). Crafting (in general) includes equipment upgrades, traps and potions. Stealth elements are presented, but it makes significant difference only on high difficulty and skill level.

Choices have lasting consequences and affect story and gameplay to some extent. Some decisions are forced for the sake of the narrative (e.g. you can't say "No" during the initiation). There are usually several ways to resolve quests. Decisions from Mars: War Logs aren't carried over.

Controls are customizable and comfortable. No support for 5 button mice, unfortunately.

Graphics, soundtrack and VA are good.

Cons: there is some backtracking and enemy respawn time is rather short.
