Sony could launch its PlayStation subscription service this week, if the latest report is to be believed.

The rival to Xbox Game Pass, codenamed "Spartacus", has been touted for a while but could now see the light of day.

"People familiar with the plans" have told Bloomberg that it will debut with a lineup of hit games from recent years, but don't expect it to be as extensive as Game Pass from the off.

According to previous reports from both Bloomberg and industry insider Jeff Grubb, the service will combine PlayStation Plus and PS Now and offer three levels to subscribe to. The first, and most basic, will effectively be PS Plus as we know it, granting access to online multiplayer and a few games for free each month.

The next, middle tier, will seemingly add a library of around 300 games that you can download and play at no extra cost while you're a subscriber, which sounds just like Game Pass Ultimate.

A third level, though, will also offer a roster of classic games from prior PlayStation eras, from the PS1, PS2 and PS3, which won't be easily accessed outside of the service. That's a potential USP and one that could generate some buzz if it's accurate.

These tiers will allegedly be called Essential, Extra, and Premium, and will cost $10, $13, and $16 respectively each month.
