So I imagined the aliens can also crash into your underground base with drop pods like
Halo.
I would say those can be late in the game for the elite Mutons saved for the dirtiest operations in the universe, when were holding our own after they've thrown so much at us. You even do Chryssalids in drop pods just like the Combine did in HL2 for infesting rebel strongholds and cities.
Anyways, they'd land scattered all over the base map and after barely winning that battle, you'd end up filling the empty spaces in the base since now the aliens can crash in scattering all over instead of using the top entrance like dead aliens into a meat grinder.
I'd also like for my operatives to be facing any nearby aliens, it would only be fair since they face the Skyranger's walkway when we attack them. Don't forget to add little pods right next to them, and covered in smoke.
