The only way I am getting through months right now is repeated raiding of a Nest in Australia. I can not destroy it, but I can crush it's surface defences and sometimes even clear B1, getting around 300 points each time.
Nests are good source of points. I am able to clean young nest, and clean surface and next two levels of adult nest (in this case with some saving and lot of luck - crystal with lightning spell is just disaster because I do not see a way how to avoid/dodge/resist it's atack)
If I compare it to TWOTS (a great mod for XCOM2-TFTD) I miss several mechanic
1] damage types
- in TFTD in a year you can get a great variety (melee, acid, stun, gauss, explosive)
- in XCHR you just have kinetic, melle, stun
(some weaopons have other effect but uses kinetic melee atributes for checking hit]
2] tanks
- in TFTD you get early some tanks that can explore and tank a damage
- in XCHR i did not find yet (ateter two years) a path to gain tanks
3] effective armor
- in TFTD you get quite soon a good spectrum of armors that can soak some damage and prevent you from being 1 shoted.
- in XCHR most armors does not protect much (I supose there coud be source of this by underestimating bonuses from enemies stats ) first hit cut down (air/water shield ) second one kills .
