It’d be nice if as the game progresses the alien mist grow in power and ability. By way of examples, it could:
- Become more effective at obscuring vision
- Spread further or quicker
- Take longer to dissipate
- Induce more loss of will in human force
- Have the ability to reduce or redirect the movement of those within it
- Consciously start to follow human forces (this in particular would be great to see)
- Prevent humans from hearing anything outside/within it
- Develop an ability to corrode armour
