Tower 57 is available on PC (Stream, GOG.com), PS4 and the Next Gen Amigas developed by Pixwerk & published by 11 bit studios.
It's a retro looking twin stick shooter where cooperation is important and you control a 3 headed task force. You need to complete tasks and and missions. It's a modern take on what old Amiga games used to look like. Chaos Engine from the Bitmap brothers comes to mind, as well as SmashTV.
It features an isometric 16-bit pixel graphics style, has wonderful music that goes well with the game. It is best played with a controller that has two analog buttons, two shoulder buttons and triggers as well as four action buttons: ala xbox, xbox360, DualShock Playstation controllers or Logitech rumblepad controllers.
In this video I try the game for the first time, it's not my most talkative first impressions video but I was just in awe of the game.
P.S. They're also working on a Linux version!
