How to run multiple accounts on DD2

A guide on how to run multiple accounts to double any amount of loot gained.

Introduction

Hello.

This is a quick and easy guide on how you can run with multiple accounts on the same computer for increased loot. This guide a DD2 spin of Acen's guide for DD1.

This is basically a emulation of running the game on a laptop next to you. Thus you will need a second Steam account with the game. The rest I can help you with.

Update november 2021: The method initially described turned out to be a convoluted and inflexible way. I have since simplified the guide with a method that's easier, simpler and takes up no unnecessary space on your disk. In short I've changed it to give the sandbox-software access to your main steam library-folder. Thus updates won't break the sandboxed instances of DD2 as with the old method. Enjoy :)

Update 15th of december 2021: With the christmas update Chromatic nerfed pristine motes acquired from chaos 8. They used to drop 9 per map and are now down to 6 per map. This change is uncalled for and if you share this sentiment I recommend voicing it on their update page, which can be found here[forums.dungeondefenders.com]. All the more reason to use an alt, I guess.

Update 2024: Chromatic has now explicitly stated that only 1 alt is allowed.

Walkthrough - Steam and Sandboxie

1) Download Sandboxie-Plus. You can find their website here [sandboxie-plus.com].

2) Run the program and create a new sandbox. Call it Steam.

3) Give it access to your Steam-folder in the settings tab.

4) Right click Steam.exe (I recommend send to desktop/create shortcut from the Steam.exe. This will make it easier to run at the start of your farming session) and click "Run sandboxed". Chose your sandbox You should notice everything that runs inside a sandbox will have have # surrounding the name and will have a yellow outline when dragging the window.

5) Log in on your second account.

Running two instances of DD2

UPDATE: This step is no longer necessary as the launcher has been removed all-together. Simply launch DD2 from the Steam window in your sandbox and it will launch properly.

This section is where the guide deviates slightly from the DD1 version. If the launcher of DD2 detects another instance of DD2 running it will not let you start up the game. If we bypass the launcher, we bypass this obstacle. Chromatic has actually provided a solution for this in their own helpdesk. You can view the thread here [chromatic.zendesk.com] if you would like to see it the whole thread. However all the solution does is execute the DunDefGame.exe, so that's all we need to do:

It's very simple.

Setup (once)

Create a shortcut for DunDefGame.exe (located in SteamLibrary\steamapps\common\Dungeon Defenders 2\DunDef2\Binaries\Win32) to desktop.

Launching the game (every time)

Right click the DunDefGame.exe and launch it through the sandbox. You can also use this to launch your main instance of DD2 by opening it normally.

Finishing comments

The guide-part is over. Here's some talk.

There are two main advantages of this. Firstly - double the loot. Secondly - you can use this to do AP-resets, where your 2nd account is floor 120-viable and just carries your main over and over again.

Of course I'll read comments so don't hesitate to ask a question or share your thoughts and experiences with the rest of the class. In particular if anyone has a shortcut to getting your alt into C8-games right away as playing through many low tier maps is boring.

@LemonAndLime - Sandbox options -> Ressource access

[LemonAndLime]

how can i give it access to files?

[NoTalker_]

Now I need a script that drops all the alt account mana CTRL and M then readys up G but idk how to write a script or find one. Any information on that?

@Beebsis - Try updating Sandboxie. That worked for me when I got the same error.

[Beebsis]

Can't seem to make this work. Keep getting "Initialization of the dynamic link library SbieDll.dll failed. The process is terminating abnormally".

@Z - On your Alt's Steam, you click Steam and then select Change Account...

Then another window appears and you click the + and login with your 2nd.

I mention how to do this in my Sandboxie guide.

Tried this three times now, I just get the sandboxed version of Steam trying to open on my main account. No idea how to run a second steam.

The Discord will allow you to have an alt, but you cannot discuss Sandboxie there as it is a 3rd party program and most game companies don't want to get their hands dirty on that shit. Also, UMedic recently got banned for running a total of 6 accounts all at once while he was farming. For the sake of safety, it is suggest to keep at most 1 alt and just get that alt to AP50 with the assistance of your main.

[M3rc!_33#]

You could give discord a shot. Some people say Chromatic allow 1 alt (which is meaningless and arbitrary. There is no functional difference between 4 accounts on 1 computer or 1 account of 4 computers but I digress...) so you're fine. Then when/if you get it to work, you can just apply it to as many accounts as you want.

That's the neat part. It didn't gave an error. It said running in green, but nothing came up, and the process couldn't be found on ubuntu's task manager thingy.
This morning I screwed around with the gui version of firejail, i managed to start the game twice, but it was hella slow. But it couldn't be my PC's issue because with sandboxie I've had no performance issue. Maybe it wasn't using the correct GPU driver, because when games eat all my processors capacity, it's usually because it's trying to use a basic ass driver instead of the dedicated NVidia driver.
But thanks for your reply anyway.
Should I ask around in the official discord, or is it too risky?
