Murdered: Soul Suspect
Developer: Airtight GamesPublisher: Square Enix
All right, so this one is not exactly indie, but I was surprised by how underrated this game is, considering it's very gripping and immersive. It might be light on game mechanics, but it does a fantastic job with its narrative as it takes you on an investigation of your own death through a dark, rundown town, and that's exactly where the focus of the game lies.
Ghost 1.0
Developer: Unepic_FranPublisher: Unepic_Fran
An excellent and highly entertaining metroidvania style platformer where we play as a female cyborg and infiltrate an enormous space station. Stunning visuals, nice music, abundant humour, challenging boss fights, and an ability to possess other machines - all make this game a great experience.
Blues and Bullets
Developer: A Crowd of MonstersPublisher: A Crowd of Monsters
A deeply cinematic detective game with a gritty and morally grey story, really unique-looking visuals and a memorable soundtrack. The game is episodic in nature and only the first 2 episodes (out of 5) are currently out.
Earn to Die 2
Developer: Toffee GamesPublisher: Not Doppler
A fun sidescrolling driving game where your goal is to improve your vehicle so that you can drive further past a plethora of obstacles and zombies until it breaks. After every few checkpoints, you unlock new vehicles to tackle on harder tracks.
Bastion
Developer: Supergiant GamesPublisher: Warner Bros Interactive Entertainment
An isometric action hack and slash with RPG elements, pretty visuals, nice music, and a cool narrator. An awesome variety of weapons and special skills make this game a load of fun.
State of Anarchy
Developer: Andrew JrPublisher: New Reality Games
A short, light-hearted top down shooter in the style of old-school GTA games, but with a twist. The visuals are all made to look like kid's drawings and all the sound effects use mouth noises.
