Dark Souls Remastered launches for PS4, Xbox One, and PC later this month, but some players will have the opportunity to try the game out ahead of its release. Bandai Namco has detailed its upcoming network test for Dark Souls Remastered, which is scheduled to take place next weekend on PS4 and Xbox One.

The network test will only be held on two days: May 11 and May 12. It begins each day at 6 PM PT / 9 PM ET and runs for approximately four hours, concluding at 11:59 PM PT / 2:59 AM ET. The test is set in the Undead Parish area and allows players to summon partners or invade other players' games.
