There’s two parts to this. The first is that in addition to the free PlayStation Plus games for April, Sony will give two free games to all PS4 owners. These games include Uncharted: The Nathan Drake Collection (which is technically three games) and the absolutely fantastic Journey.
These will be available from this Thursday (16th of April) until the 6th of May. This is to ensure that people that are staying at home as well as new PS4 owners have access to entertainment to help keep them occupied whilst isolating.
