over the hill multiplayer: co-op, crossplay, local status

The multiplayer design is straightforward on purpose. You and up to three other players can drive, explore, and progress together across the same off-road biome slice. The Steam store page describes up to 4-player online co-op as the published ceiling, and the official Reddit FAQ confirms that this 4-player ceiling is the shipped multiplayer scope rather than a target.

Key facts about the multiplayer loop:

• Player count: 4 players including the host, confirmed by the Steam store page.
• Matchmaking: party-based co-op, not a public matchmaking lobby, per the official Reddit FAQ.
• Persistence: shared world progression — meteorites, objectives, and unlocked vehicles are common across the party, as described by the Forbes preview.
• Voice and chat: in-game proximity chat has not been formally announced; players typically use Discord or platform-native party chat, which the Steam Discussions crossplay thread treats as the practical baseline.

Crossplay is fully supported across the four launch platforms. The official Reddit FAQ and the Steam Discussions crossplay thread both confirm that a PC player can join a session hosted on PS5, Xbox Series X|S, or Switch 2, and vice versa, with no platform barrier. Forbes describes this multiplayer setup as the heart of the game's "cozy multiplayer" pitch.

A platform-specific filter or "prefer same-platform" option was Not announced as of 2026-07-25. Players in different regions can typically play together as long as both regions are supported by their storefront.

Local couch co-op and split-screen were Not announced as of 2026-07-25. The Steam Discussions local co-op thread is a long-running community request, and the Steam store description does not list split-screen as a feature. Forbes' preview (forbes.com) frames the game around online co-op rather than local couch play.

What is confirmed:

• Online co-op up to 4 players with crossplay.
• Controller support across platforms, with the Forbes preview noting that a controller is strongly preferred over keyboard and mouse.

What is not confirmed:

• Local couch co-op on a single device.
• Split-screen rendering on PC, PS5, Xbox Series X|S, or Switch 2.
• LAN co-op without an internet connection.

If you specifically want to play over the hill on a couch, plan for two consoles on the same network with online co-op, since local co-op is not the shipped mode.

The Steam Next Fest demo (June 12–22, 2026) supported the same 4-player online co-op as the full game. The official Steam Next Fest news post is the source of record for the demo window. Demo save progress carry-over to the full release was Not announced as of 2026-07-25, so a fresh co-op start is the default at launch.

For controller setup, the Steam Discussions controller thread tracks an early demo-era bug where some controllers were not detected on first launch; restarting the demo or the Steam client typically resolved the issue, and the developer posted an official reply acknowledging the investigation.

Multiplayer choices ripple into other decisions a new player will make. If you want to try co-op before launch, the Steam Next Fest demo guide explains the install path and what is included. Once you have your convoy, the vehicles hub walks through the demo-confirmed and community-collated vehicle roster. If you plan to play co-op on the go, the Steam Deck guide covers Proton prefix, performance presets, and controller behavior.
