SEAF Companion 0.11.2 Alpha

A Mod for Helldivers 2
SEAF Companion akl_mod_preview_image
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.

Not using this mod because I only play multiplayer, but I am here to say that I love the idea and am glad it exists.

WOOOOOO! (still not sure how I feel giving up a stratagem slot for Doc, but hey, SEAF are SEAF. The dream stratagem would be Doc the first time, SEAF drop in the rest of the time. IDK if that would be a bit strong tho, probably not.)
It comes to the fact that doc with frv is lot more stronger than any two sentry strategems. Cause its autoaim and ammo keeps refilling as long as doc mans the gun.

If possible,SEAF on the ship can interact with Jedi submarines.
如果可以的话,我希望在舰的SEAF可以与绝地潜兵进行互动

I've made a good friend, haha. I really wish this SEAF-Doc Chan would also transport ammo for the SEAF artillery.

i wonder if it is possible to compliment this mod for it to work with tanks as well? or maybe somehow make it so that all seaf soldiers can enter vehicles or drive them on their own via commands or pings

Please consider that he only stays on the gun when you're driving the FRV and thus unable to do anything. And also, not eveyone may want to use the FRV with a SEAF companion. The FRV doesn't need to have infinite ammo either, you could even make it a toggle. He's also dumb and will run at the FRV endlessly or shoot into walls/floors. Would be so cool if he could use emplacements I call down, or even a tank. I'm suprised that he just teleports into the FRV gun , I thought it would be more like you ping it and he runs up to it, then gets in.

If you want to flesh this mod out, go look at how you could interact with Halo Marines. That would be epic in HD2.

I'm unsure about the bug, I've been using him primarily during sc farming. Did you dive in the same mission twice after abandoning? Cause when you collect sc from a mission and replay the same mission it doesn't give you the rewards.
I wrote this using a translator.

I think you are right.

I updated your mod and tried again, and I was able to acquire it without any problems. I thought I had done a lot of SC farming before, but this is the first time I've encountered this. Thank you again for the great mod.
