Serious Sam Fusion, the game hub that allows you to play Serious Sam HD: The First Encounter, Serious Sam HD: The Second Encounter, Serious Sam 3: BFE along with the VR version finally has an update. It's still in beta, but not classed as "Early Access" on Steam.

If you pickup any of those games, it automatically gives you Fusion which is especially good for Linux gamers since some of their titles weren't officially available on Linux but are with Fusion. The Fusion hub also brings Vulkan support, so that's awesome.

Here's the most major changes in the fresh release:

Fusion now has its own menu and game title as default, the game no longer launches with the SS3 menu settings. As such, the SS3 intro now plays when the first level of SS3 is started.

Added new default gamepad layout (classic one is still available as option).

Added a new weapon wheel that slows down time when used to select weapons.

Added a new Bloom system.

Menu now properly scales on 4K resolutions.

Many other smaller changes.

Speaking about how this update to Fusion took so long, going by their news on Steam it was a hotfix way back in February, they said this:

Fusion is a central hub that connects all the main Serious Sam games in one and allows regular and VR players to jump in to the game together. Fusion also brings many improvements to previous games including a brand new engine - the same one Serious Sam 4 will be based on. This development path brings with it various potential hickups, many of which we have experienced during the preparation of this patch. However, we are finally at a point where Fusion can be branched out as a stand-alone project, so SS4 development will no longer make its code unstable. Unfortunately due to this, the patch will re-download and re-install your game from scratch. With all games available, this makes the download around 12 GB.

Currently it seems to work fine, apart from the graphics options menu crashing to the desktop every time for me. Unsure if it's a bug or a problem on my system but I've let them know anyway.
