Supported Maps
From ALiVE Wiki
If a map is not indexed, you can still use Custom Objectives, CQB and some of the Support Modules. You can also place units manually and sync them to the Virtual AI system. Placement modules will not work.
The best source of accurate information is of course the map indexes themselves in the ALiVE Static Data folder
The Discord community maintains this spreadsheet although there is no guarantee it is fully up to date. Ping us on Discord if you want to help maintain it.
You can submit requests for the community to index new maps using this form, though bear in mind it's a community effort and it make take some time.
