Plan your next Serious Sam Fusion 2017 (beta) session

Our independent guide examines how Serious Sam Fusion 2017’s unified launcher, cross‑title multiplayer, and modern platform features affect everyday play. By comparing each new system to its predecessor, you can identify where the beta adds convenience and where extra testing may be needed.

01 / THE GUIDE

Launcher Efficiency

Start a level in The First Encounter, then switch to a Serious Sam 3 map without exiting the application. Note load times and any UI differences to gauge the hub’s convenience.

  • Use the hub to test different game styles without reinstalling each title.
  • Keep the hub updated to receive the latest engine improvements.

02 / THE GUIDE

Cross‑Game Server Navigation

Browse the combined server list, join a match hosted under a different title, and vote for a map not native to that game. Observe how map voting integrates across titles.

  • Check the combined server list to find populated matches quickly.
  • Vote for a map from another title to experience varied level design.

03 / THE GUIDE

Controller Compatibility Test

Connect a PS4 gamepad in one session and a legacy DInput joystick in another. Compare responsiveness and any configuration steps required by Fusion.

  • Experiment with different controllers to find the most comfortable setup.
  • Enable borderless window mode for smoother alt‑tabbing during split‑screen sessions.

04 / THE GUIDE

Cloud Save Validation

Create a save, apply a patch, then reload the save on another machine. Confirm the save persists and reflects any level changes introduced by the patch.

  • Verify cloud sync after major patch installations.
  • Use the fast save feature to capture progress before testing new mods.

05 / THE GUIDE

Mod Integration Review

Install a workshop mod that adds a new weapon, then launch a single‑player level to verify the weapon loads correctly. Note any scripting messages that appear.

  • Browse the shared workshop to find mods that work across multiple Serious Sam games.
  • Test scripted mods in a single‑player session before joining multiplayer.
