Open Annihilation, the community engine for Total Annihilation, now lets players share custom key layouts. Its 0.8.7 release also adds a way to undo engine updates on Windows, macOS and Linux.
The engine runs the 1997 strategy game using its original data. The release notes say players need an installed copy of Total Annihilation with the 3.1 update, or the free 1997 demo. The engine comes with no game data.
The key editor lets players assign game and menu actions to keys or mouse buttons. It warns when two actions share a key. Players can save a layout as a file or copy it as text to send to someone else. Escape still closes chat and the engine's own screens.
The desktop updater keeps the previous engine version and its settings, so players can restore both. The release notes say it asks before installing an update. If a new version fails to start twice, the old one returns on its own.
Mods can now exceed the original limits of 256 weapon types and five sides. A mod that raises either limit can only be played between Open Annihilation machines. Someone using the original game cannot join those matches.
The notes also flag a change for older saves and match recordings. Those from version 0.8.6 or earlier that include a unit being repaired may no longer play out exactly as before. The update changes which unit pays the repair cost.
