Helpful Information
- You can be in all factions at once if you want to.
- I have marked the only times where a faction will turn permanently hostile.
- You obviously don't want to go into a faction's base and start shooting them and this will make them hostile but not permanently.
- There's only two saves you need to make i.e before "Mass Fusion" and before "End of the Line"
