Grenade damage is 50, grenade launcher HE is 48. This has not changed in the last couple of years at least. I have not played FMP, but looking at the rulesets, those are the same. So there's no real difference, though the blast radius of grenade is 5 instead of HE grenade's 4. Both have damage spread of 50-150 %. With this kind of damage you can't really depend on even weaker cultists dying of one hit, though the weaklings often do.
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.
it does not make sense to directly target enemies with grenade launcher. If you score a direct hit, your unit is marked as spotted and enemy sniper units can fire at the unit or throw grenades at it even though they don't see your unit. Throwing grenades does not have this issue, and you can also target an adjacent tile.
Thanks for tip! Which I assume related to any shooting weapon? In any case this make throwing grenades even more overpowered than I thought.
Personally I used GL in FMP simply as much faster (and reliable in rough terrain) RL variant.
I'm not sure if grenade launchers still hit the under armour on direct hits or if they hit the front armour instead, if that is the case then it could explain direct hits being weaker than expected but I'm probably wrong on that as don't know the explosion mechanics
Not much an issue for low level enemies.
