Developer GuFugu released 0.0.4 on October 31. This page summarizes the official notes and points you to the right place to play. The downloadable Windows release is confirmed as 0.0.4; the version of the separately hosted browser build has not been verified.
New air and ground roles
The bomber drone is a playable soldier class that drops grenades over enemy positions. It differs from the FPV drone, which flies into its target. A new shotgun class is intended to defend infantry against drones. The release also adds grenade types used by infantry and bomber operators. The official notes do not list every grenade type or control, so check the current in-game menu for those details.
Sound, performance and fixes
Steam Audio now handles sound with surrounding spaces and room acoustics in mind. GuFugu says calibration is ongoing, so audio issues may still occur. The release also adds heavy-vehicle sounds, improves blood effects and AI, expands settings, fixes interface icons, and includes optimization and bug fixes.
Which version should you play?
For the confirmed 0.0.4 release, use the developer's official Windows download. This site also embeds a separately hosted Unity WebGL build for browser play. We have not verified that its content matches 0.0.4, so new features may differ there. The game expects a keyboard and mouse. GuFugu has stated that a mobile version is not planned.
