Whether you describe GET EVEN as a story-driven "walking simulator" with combat elements, or first person shooter with a strong story is debatable (I'm personally more in the former camp), but either way the story is the focus here.
If you've seen movies like Source Code (especially) or Inception you'll have a good idea of what to expect from this game story-wise (a minor spoiler perhaps), although the execution/presentation is more like a standard, very linear oldish FPS game (i.e. before the advent of scripted "set-pieces"). As well as more traditional cut-scenes, there are numerous in-game scenes that play out in a The Vanishing of Ethan Carter or Everybody's Gone to the Rapture style manner.
The game's M. Night Shyamalanian twisty story revolves around examining memories presented in first person in order to attempt to piece together a complex narrative revolving around why a bomb was strapped to a young girl. Most of the game is played as a mercenary who was intimately involved in a plot that involved the theft of a revolutionary weapon and subsequent revenge by its corporate owner, as well as some double-crossing, an affair, and culminating in the kidnapping of the girl. Explaining how this all fits together would spoil the main thrust of the game, which is story-telling. It would be amiss to not mention the superb voice acting that completely nails the game's core intent.
The PC version is stable with graphics typical for indie games based on the Unreal 4 Engine (i.e. neither great nor terrible). Easily playable on a potato, I'm pretty sure with the various graphical settings one expects on PC titles. The only serious bug I encountered numerous times was getting "stuck" on corners, i.e. not being able to move and thus forced to reload the last checkpoint - nothing game-breaking, but still annoying. All keys can be rebound, which is useful for left-handed players. While you can crouch, there is no jumping, which may feel strange for players familiar with standard FPS movement mechanics. There are also a handful of fairly simple environmental puzzles that shouldn't be too challenging for experienced RPG players (needless to say, YouTube will help you here regardless).
If you're a fan of story over gameplay, and don't mind occasional shooty shooty bang bang and puzzles to break things up, there's more than enough here to recommend this game, especially considering it's budget pricing and ~10 hour play-through.
