MafiaCoop 0.15.0 (pre-release, mostly not yet verified in game)

Pre-release. Most of what is new is not yet verified in game. 0.15.0 had a first test on one PC (two copies of the game, Free Ride, CHAPTER 2: TAXI, the start of CHAPTER 13: SALIERI). Verified there: car signals, failed missions in one load, and the police fix. Everything else below is written but not yet verified in game, and the test found some problems (see Known issues). Read them before you play.

Download MafiaCoop-0.15.0.zip, extract it anywhere (not into the game folder) and run MafiaCoop.exe. The zip's README.txt covers requirements, hosting and joining, settings, the optional start-from-Steam mode and uninstalling. MafiaCoop-0.15.0-symbols.zip holds the PDBs and is only needed to read crash dumps. Everyone needs 0.15.0: the messages and the protocol version changed, so 0.14.0 can't join.

Requirements

• Windows 10/11, 64-bit
• Mafia: Definitive Edition that you own on Steam, Steam build 16502642 (the current one); Steam running
• Everyone in a session on the same mod version; joining by IP needs UDP port 27960 open on the host

Verified in game

• Car signals: headlights, indicators, horn, siren and police beacon of the car another player drives show on your screen.
• Failed missions take one load: no more short stop in a Free Ride world. When the host fails, everyone goes back to his checkpoint with him. When a friend fails, the host decides whether he rejoins at once or waits. Checked for the host's and the guest's failure in Taxi.
• Police fix: a wanted friend no longer makes the host wanted.

New, not yet verified in game

• Fights and moving around:
  • Punches, counters, takedowns and throws are sent to the other players' characters. The punch itself doesn't show yet (see Known issues).
  • Jumps, vaults, ladders, cover slides, sneaking, the medkit and carrying bodies show on the other players' characters.
  • Enemies only a friend's game spawned now show on the host's game too.
• Cars:
  • The other player's character stays in its seat. Riding along waits until the driver sits at the wheel.
  • A mission car replaced by a copy comes back when the driver parks and gets out.
  • Near the host, a friend sees the host's traffic and police cars.
  • Dents, parts, tyres, fire and explosions show on every game.
• The world:
  • Doors are shared: open, close, kick, unlock and lockpick.
  • Weapons on the ground and pickups are shared, and the host decides who takes them.
  • Explosions show on every game as a harmless picture, and a grenade's flight is drawn on the other screens.
  • Wanted levels are shared, and the host's police chase a wanted friend near the host.
• Map: every other player is on your minimap and map with his name, on foot and in a car.
• Connection:
  • Reconnect: a dropped player's game rejoins by itself for up to a minute and gets his place back.
  • Three or four players.
  • Lower latency (core 0.11.0).
  • JOIN FRIEND lists your Steam friends who play and what they're doing.
• Gamepad: a real controller works in the co-op panels, and the footers show pad buttons or key names, whichever you use. Fixed after the test: closing a panel with a pad button no longer blocks the keyboard on the loading screen.

Known issues (from the test)

• Punches don't show: punches and throws don't show on the other player's character. The real hit still lands.
• Map marker: the other player's marker couldn't be found on the minimap, although the logs say it's there.
• Car look: a player's car shows as another variant and colour of the same model on the other screen.
• Damage after an explosion: after a car blew up, the host's game took the copy's damage report as a repair.
• Seats after a reload: after a friend's game reloads at a new checkpoint in a car, the host may see the friend's character hidden in the car instead of seated.
• Police level: a wanted friend's level runs down on his own game while the host's police chase him.
• Garage: a co-op CHAPTER writes the player's garage (garage.pf in the profile). Your story saves are never loaded or changed.
• Not tested yet:
  • doors, items, enemies only a friend's game spawned, and the mission car coming back after parking
  • three or four players
  • two PCs over Steam
  • a real gamepad
  • JOIN FRIEND with a friend
• After a test, zip the whole logs folder on both PCs and send both.
