Here is an overview of the mode, via Oculus Studios:

In “The Mercenaries,” you’ll take on waves of Ganados across a variety of levels as you endeavor to rack up points in your battle to survive. There’s a timer ticking down with each passing second before a helicopter comes to rescue you, so you’ve got to get as high of a score as possible (and stay alive!) until the timer runs out. Each map has extra time pickups hidden in various nooks and crannies to keep you going, but it’s definitely not easy. And in The Mercenaries, you’ll be able to hop into the shoes of not just Leon, but also iconic characters like Ada Wong, Albert Wesker, Jack Krauser, and H.U.N.K. all in first-person virtual reality.

In addition, “The Mercenaries” is getting a few additions for its virtual reality debut. In this new version of “The Mercenaries,” players will be able to claim their spot on ranked online leaderboards and even take on 20 all-new, made-for-virtual reality Challenges. In Challenges mode, we introduce wild scenarios and restricted conditions for completing levels to ramp up the intensity. Some examples include getting high scores using nothing but a knife, a mysterious fog impairing your vision, or even special circumstances that restrict time even further.

By completing Challenges, you’ll unlock all sorts of awesome things like a Big Head Mode, a black-and-white Classic Horror Mode, Fast Forward Mode, or even new Golden Gun skins that were custom-made for virtual reality players. All of which can be used in the main game.

Resident Evil 4 VR is available now for Quest via Oculus Store.
