Nom Nom Galaxy (PS4)

Persona 4 Arena Ultimax (PS3)

Grid Autosport (PS3)

All six games will be available from next Tuesday, February 2.

ORIGINAL STORY: PS4 games Helldivers and Nom Nom Galaxy will be available to download for free on PlayStation Plus next month, Sony has announced.

The two games are listed under the PlayStation Plus tab on the PS4 home screen (pictured above), although it isn't yet clear which games they'll be joined by on PS3 and PS Vita. Expect an official announcement soon.

Both games will be available to download from February 2. That means you have less than one week to grab the current line-up of free titles, which includes Grim Fandango Remastered and Hardware Rivals.

Helldivers launched on PS4 in March 2015 and was well received for its top-down sci-fi shooting. Nom Nom Galaxy, meanwhile, is described as a "genre-blending" game involving platforming, mining, building, tower defence and resource management.
