How to install and setup ERA Project (WoG) via Heroes Launcher

The ERA Project picks up where the development of ERA 3 left off—or rather, where it began to stagnate. Essentially, the ERA Project is Wake of Gods (WoG) in its best and most refined form.

Right out of the box, it includes pre-installed modifications that allow you to play on massive XXL maps, enjoy improved graphics, new scripts, new battlefield terrains, an enhanced map and campaign editor, an upgraded user interface, and much more.

You can download the ERA Project as a standalone package, or install it via the Heroes Launcher—which is the best option, as it offers future updates that can be installed with just a single click.

  • Fixed a desynchronization bug in PvP network combat that occurred when one client’s CPU supported SSE 4.2 while the other did not. The two systems were using different CRC‑32 hashing algorithms, which caused mismatched state updates.
