Sony has revealed the games it will be offering to its PlayStation Plus subscribers for free in the month of May. Included among them are Guacamelee, The Unfinished Swan and Ether One, all of which are coming to PS4.

Ether One is a first person adventure game made by Manchester-based development team White Paper Games, who have been working on a PlayStation version since the game first released on PC roughly a year ago.

Guacamelee meanwhile is a colourful and boisterous Metroidvania style adventure about a luchador wrestler fighting evil forces in a stylised, Day of the Dead-themed world. It was a critical success upon its initial 2013 release and was released on PS4 last year.

On PS4 also comes The Unfinished Swan (as well as PS3 and Vita), an experimental game in which the player is presented with pure white world rendered in 3D which they must navigate through splashes of colour. Developed by Giant Sparrow, the game was first released on PS3 in 2012.

Also coming to each of the three platforms is Hohokum, a colourful and celebrated art game, and Race The Sun, in which you must pursue sunlight in a jet to keep your ship powered. Finally coming to PS Vita only is Ovosonico's Murasaki Baby, another stylished game about a little girl finding her way home.

These games will go live from 6 May.
