Quick Answer

Steam currently lists Single-player, Online PvP and Online Co-op support. You can verify those categories on the official Steam store page and in the official Steam appdetails data .

PvEvP describes the raid threat mix and should not be presented as a fourth Steam mode category.

Use this breakdown:

  1. Single-player: confirmed by Steam.
  2. Online Co-op: confirmed by Steam.
  3. Online PvP: confirmed by Steam.
  4. PvEvP: a description of environmental/infected and player threats existing in the raid experience, not a fourth Steam feature category.

Single-Player

Single-player is officially listed.

That confirms that playing as a single player is supported. The feature label does not establish extra rules such as offline-only play, a unique solo progression system, or a dedicated PvE-only ruleset.

For anything beyond the feature label, follow what the current game build actually shows.

Online Co-op

Online Co-op is officially listed.

That confirms cooperative online play. The official feature listing used here does not establish exact party size, host rules, matchmaking behavior, or special progression rules for co-op.

If co-op is available but you have a technical problem joining or spawning, use Issues . Mode support and a technical failure are separate questions.

Online PvP

Online PvP is officially listed.

That confirms player-versus-player support exists. The feature label does not establish exact encounter frequency, matchmaking rules, penalties, protected zones, leaderboard systems, or universal combat conditions.

Those mechanics should not be inferred from the Steam label alone.

What PvEvP Means

PvEvP describes the mix of threats inside the raid experience.

The distinction is:

  • Environmental or infected threats make up the PvE side.
  • Other players create the PvP side.
  • PvEvP describes those pressures coexisting.

It should not be presented as a fourth Steam mode alongside Single-player, Online PvP, and Online Co-op.

How To Choose a Play Option

Playing Alone

Single-player support is confirmed. Use the current game interface for any rule that is not stated by the Steam category.

Playing With Others

Online Co-op support is confirmed. If you want to know whether co-op also means a dedicated PvE-only environment, see PvE .

Player Conflict

Online PvP support is confirmed, and the game is described as PvEvP. Do not infer exact PvP rules beyond that.

Mode Questions To Keep Separate

These questions sound similar but are not identical:

  • Can I play alone? Single-player is listed.
  • Can I play cooperatively online? Online Co-op is listed.
  • Does the game support PvP? Online PvP is listed.
  • Are environmental or infected threats part of raids? Yes, the game is described as PvEvP.
  • Is there a dedicated PvE-only mode? The checked official sources do not establish one.

Mode Decision Route

  1. Choose Single-player when you want the listed solo option.
  2. Choose Online Co-op when your next action is to play cooperatively online.
  3. Choose Online PvP only when you want the listed competitive online option; PvEvP describes the threat mix rather than a separate fourth mode.
