Retro PlayStation games started appearing on PlayStation Network main servers ahead of the new PlayStation Plus service.

When it launches in June, the new PS Plus will be a three-tier service, with the top tier adding access to up to 340 retro PS1, PS2, PS3 and PSP games (with streaming PS3 games only).

Reddit user the_andshrew found images and title IDs for five of these games, suggesting that Sony is currently adding the new retro library to its servers.

The five games that have been spotted so far are:

• Mister Driller (PS1)
• Tekken 2 (PS1)
• Ridge Racers 2 (PSP)
• Towards Armageddon (PS1)
• World Worm Party (PS1)

It was also spotted last week that four classic Siphon Filter games were rated for PS4 and PS5 in Korea.

Siphon Filter, Siphon Filter 2, Siphon Filter: Dark Mirror and Siphon Filter: Logan’s Shadow have all received ratings, suggesting they will also be part of Sony’s upcoming retro library.

Launching in June and structured in three payment tiers, the new PS Plus will combine existing PS Plus and PS Now subscriptions, phasing out the latter’s branding.

PS Plus Essentials offers the same benefits as the current PS Plus service, with monthly free games, discounts and online multiplayer. It will also cost the same price: $9.99/€8.99/£6.99 per month, $24.99/€24.99/£19.99 for three months, or $59.99/59, €99/£49.99 per year.

PS Plus Extra will include the same benefits but with access to a library of 400 downloadable PS4 and PS5 games. It will cost you $14.99/€13.99/£10.99 per month, $39.99/€39.99/£31.99 for three months, or $99.99/€99.99/ £83.99 per year.

PS Plus Premium will include the above benefits but add up to 340 additional games, including PS3 titles available via cloud streaming, and a catalog of classic games available for streaming and download from PSOne, PS2 and PSP generations .
