Undercoop: NFSU2

Undercoop: NFSU2 — a co-op mod by batuhan that adds two-player co-op to NFS: Underground 2. Players drive through Bayview together: a shared career with sponsors, unlocks and Special Events, free roam with traffic and AI rivals, as well as Circuit, Sprint, Drag, Drift, Street X and URL races.

What's inside

• Shared career: progress, sponsors and special events are played through together.
• Free roam: you can just cruise around the city with a partner.
• Your own garage: each player keeps their own cars, money and tuning.
• Shared cutscenes: the story is watched together, skipping is done by vote.
• Communication: partner markers, green icons on the map, chat, ping and activity indicators.
• Backups: automatic restore points for the co-op career.
• Launcher and mod manager: import archives and folders, enable and disable packages, separate modpacks, import saves.

The mod is in open beta: bugs and mod conflicts are possible. Connection is direct over LAN or via a shared virtual LAN (for example, Radmin VPN); there is no public matchmaking, dedicated servers or split-screen. Both players need the same version of Undercoop and matching mod sets. Installation requires the Windows version of the game with the v1.2 NTSC executable and a compatible ASI loader.

How to install

1. Back up the game folder and your saves.
2. Extract the archive into the game's root folder — the one containing SPEED2.exe — keeping the folder structure.
3. Check that the files NFSU2Coop.asi and NFSU2Coop.ini are in the game's scripts folder.
4. Launch SPEED2.exe — the built-in Undercoop launcher will open.
5. Open Undercoop Settings and configure the connection before starting the game.

How to play co-op

1. Connect both computers to the same LAN or to a shared Radmin VPN.
2. In Undercoop Settings, assign one player as host (Player 1) and the other as client (Player 2).
3. Enter your partner's IPv4 address in the peer-address setting: each player enters the other's address.
4. Use identical connection settings and matching ports, and allow the game through Windows Firewall.
5. Select the same mods on both computers and press Play.
6. In game, open the CO-OP menu: one player creates a lobby, the second joins.
7. After the lobby checks, the host selects Start the Career and creates or loads a career.

Controls: Z — co-op console, Enter — send a chat message, F5/F6 — accept or decline an invitation.
