SEAF Companion gives you Doc, a SEAF soldier who stays with you across missions. He drops in with you, follows you, fights beside you, ranks up the longer he survives, rides in your FRV and mans its gun.

IMPORTANT - read before installing​

• Single player only. Do not use it in multiplayer: other players see no turret gun, Doc jitters on their screens, and stratagem changes like these have disconnected players in the past.
• Two stratagems are changed: the MD-6 Anti-Personnel Minefield delivers Doc instead of mines, and the M-102 Fast Recon Vehicle's rear gun becomes the automatic turret Doc mans. Your MG Sentry is untouched.
• They are meant to work together as one package. Doc works without the FRV, but then he can do less (no rides, no gunner mode). The M-102's gun only fires with Doc on it.
• If you want either stratagem to work normally, turn the mod off.
• Using S.E.A.F Call-In Stratagem Replacer? Set it to a stratagem other than the gunner FRV or the MD-6 minefield, and both mods work together.

Features​

• Doc drops in with you. Your MD-6 Anti-Personnel Minefield stratagem delivers a supply box with Doc standing beside it. Cooldown 60 seconds.
• Call him again if he dies. A new Doc arrives with the same rank and XP. Only one Doc at a time: calling it while he is alive brings just a supply box.
• He follows you like a native SEAF soldier and fights with his own weapon.
• Ranks and XP. Kills, following you and surviving missions earn XP; dying costs XP. There are 9 ranks, from Recruit to Sergeant Major. Each rank gives him more health: x1.5 at Recruit, up to x2.5 at Sergeant Major. Medic types also get a different uniform look at higher ranks.
• Choose your soldier. Pick from 11 SEAF soldier types: medics, troopers, squad leaders and specialists, each with a male or female voice.
• Doc on your ship. He stands in your quarters (only you see him). Press E next to him for his card (rank, XP, missions, kills, deaths). Press H on the card to change his soldier type for the next drop.
• HUD. Bottom left: Doc's health, plus the gun's rounds when you are near your gunner FRV.
• Stims heal him fully, to his ranked maximum health.
• FRV rides. When you drive an M-102 FRV, Doc takes the co-driver seat. He gets out when you do.
• Gunner mode (M-102 FRV). The M-102's rear gun becomes an automatic turret that looks like the M-102 gun. The model is included in this mod.
  • Doc stands at the gun and turns with it. It finds and shoots enemies on its own, up to 75 m away.
  • Press R in the driver's seat to move Doc between the co-driver seat and the gun.
  • The gun only fires while Doc is on it. His own rifle is put away while he is on the gun.
  • The belt keeps topping itself up, so the gun never runs dry. The gun's kills count for you and for Doc.
  • The barrel tilts up and down to aim, and rests level when there is nothing to shoot.
• Bunkers. Hold one bunker button and Doc (if he is within 10 m) goes to the other one and presses it with you.

Requirements​

• Bingus Shared Loader (the Lua addon loader).
• A mod manager, for example Helldivers 2 Mod Manager.
• Made for game build 25480438. On other game versions every engine address is checked before use, and the mod switches the affected feature off instead of guessing.

Install​

1. Install Bingus Shared Loader.
2. Add the SEAF Companion zip to your mod manager, deploy, and start the game.
3. Bring the MD-6 Anti-Personnel Minefield in your loadout. Calling it in delivers Doc.

Settings​

The settings file is %LOCALAPPDATA%\Hd2SeafCompanion\seaf_companion.cfg. It is created on first start and read when the game starts. Each setting is explained inside the file. The main ones:

• soldier: which SEAF type Doc is (or press H on his card on the ship).
• ride=1: Doc rides in your FRV.
• frv_autoturret=1: gunner mode on the M-102. Set it to 0 for the stock M-102 gun.
• hud=1: health HUD.
• ship=1: Doc on your ship.
• doc_cooldown: Doc's stratagem cooldown in seconds (default 60; 0 = the game's own 120).

Doc's rank and stats are kept in companion.cfg in the same folder. You can also rename him there: name= is his full name on his card, short= is the name on the HUD.

Known limits​

• Single player only. In multiplayer, other players do not see the turret gun, and Doc jitters on their screens.
• Doc takes over your MD-6 Anti-Personnel Minefield stratagem. Death costs him XP, but never a rank.
• The bunker helper only works in your own game (as host).
• Rank looks only change the three medic types. Other types keep their standard look.
• With gunner mode on, every M-102 you call in carries the automatic turret.

Upcoming​

• Multiplayer support: other players see the turret gun, and Doc rides smoothly on their screens.
• Rank looks for every soldier type, not only the medics.
• The bunker helper in other players' games, not only when you host.
