hive sight on cyst again! but as upgrade, not overall
Why not let khammander upgrade cyst with some tres and let them give hive-sight when marine steps its own infestation? Gonna be cool. Some cysts at some junctions and some important entrance could be upgraded and therefore give hive-sight to khammander and to the alien players, then they can predict what the marines are gonna do, and prevent or prepare against them.
Or contradictionally, marines can trick aliens if they know whether that cyst is upgraded for automatic hive-sight
