are all the patches already installed on/in this game?
or do i have to install them myself?

When you install the latest B128Hotfix4 either by GOG-Galaxy (stable and unstable branch are the same at the moment) or by the Offline-Downloader (B128HF4 Part 1-5) you are good to go.

For around middle of May the Developers announced the new Betabuild B129, which will be released (like all other Betabuilds before) initially at the unstable branch.
This new Beta shall bring some big changes.
In my opinion the care for GOG-Customers by the Developers was excellent so far.
What was released on Steam, was - sometimes a bit later - released here on GOG.

One tip: take you some time to get into the game. It looks quite complex at the beginning, but after some inglourious rides to the bottom, you will get the hang of it. Its not so complicated as it looks after all.
There is a ingame-tutorial, but not in the Main menu.
You have to start a new mission and to speak to the Officer standing next to the Uboat.
One option is "My crew needs training" or something like that and there you find some tutorial missions.
Otherwise there are a lot of how-to-do-videos on Youtube.

Have fun!

there are 4 hot fixes in my Xtras folder for this game? (three B127's)??
do i install them from the first one to the last one (B128 that is 13 GB big)??
how can i tell what version i have?
yes, i will take my time for sure. the training one sounds like a good start.
and thank you for the reply.

Yes, thats confusing.
But I´m quite sure you don´t need this three B127 Hotfixes.
No idea why they are there...

You can see your current game version in the launcher as well as in the main menu. (left/right corner below)

after i dress my captain the game does not load.
a little thing called "UNITY 219.4.15f1-fbf367 ac14e9" pops up and a green bar starts and gets about a third of the way to the end then the game crashes?
do i need some sort of unity player program installed?
i did lower my graphics and the intro ran much smoother, and tried a few different compatibility configurations but, no luck keeps crashing when it loads new game?
darn!!!

strange that i do not have "Tutorial" nor "SandBox " in my main menu like i see in some videos on Utube?
ok i misunderstood you. i tried lots of troubleshooting things with no luck. i think my video/graphic card and/or cpu isnt up to par with this game. tried different drivers. no luck.
going to try a few more troubleshoot things tomorrow. if that dont work i give up lol
thank you for your help, thought it would run okish when it booted into the intro and main menu part but after that...crash

looks like i am having a faulty direct X and a Unity .dll file.

d3d11.dll in my windows-sytem32 and a Unityplayer.dll version 2019.4.15.62311 tha is installed in the panzer elite game..

i do have directx 12 as well and a directx linking dill from directx 11 to 12 .dll.

and i dont know how to fix it lol
and they seem to work fine in other apllications.

wonder if my firewall is blocking the uintyplayer.dll, or its unsigned or corrupt?
doesnt say it is when you look at the firewalls history.
all my dlls are registered in the registry.

hours and hours trying to trouble shoot this game. i am done with it!!
sad but true.
solved
