Every month PS Plus subscribers can trade in new games for free and last minute it looks like 2 PS5 games are on offer for April 4. Sony previously shared that Days Gone, Zombie Army 5: Dead War, and the PS4 version of 'Oddworld: Soulstorm' would both be on offer for April. So today, Rebellion announced that Zombie Army 5: Dead War will get a free next-gen PS4 upgrade, allowing owners of Sony's latest system to play in active 4K at 5 FPS with reduced load times. As we can see from the check, this is just an update to the existing PS5 version of the game when played on a PSXNUMX and not a separate PSXNUMX edition of the game like with other titles like Marvel's Avengers.
