The 01.000.200 patch was a major update for Helldivers 2, introducing a bunch of mission balances, several buffs for weapons, and nerfed multiple enemies. It’s gone over well with most players, however, the title has been randomly crashing in certain instances. Arrowhead has already taken note though and has quickly released a hotfix.
The crash issue was caused in most cases when accessing the Acquisitions menu. While this has been fixed with the Helldivers 2 01.000.201 patch, devs are aware of some known and ongoing issues that are yet to be fixed that hopefully will be touched on in coming patches.
