Thanks for tip! Which I assume related to any shooting weapon? In any case this make throwing grenades even more overpowered than I thought.
Yes, it affects any shooting weapon, and melee as well. It does not apply to "area effects", so thrown grenades or splash damage from grenade launchers, rocket launchers, etc. does not trigger this behavior.
Yes, I have seen these numbers too. May be some mechanic has changed from OXC? In FMP grenade launcher do well even on aliens which are much better protected than early x-files scum.
Let's take a look at first-level cultists in XCF:
- Red Dawn Ganger: 50 health + 5 armor
- Supporter of Dagon: 40 health + 5 armor
- Black lotus follower: 35 health + 5 armor
- Exalt infiltrator: 30 health + 5 armor
So it's unlikely that you kill even an initial RD ganger with one grenade, you'll need to roll quite a bit higher than 100%. For the rest a 100 % damage roll is enough, and with some by quite a large margin. None of them are guaranteed however. In vanilla and FMP, sectoids are 30 health and 2-4 points or armor. So they are essentially comparable to exalt infiltrators. A very likely kill with one, but not guaranteed. In XCF sectoids are tougher, because they also have PSI shields.
