i have tested this mods, and .. it's really cheated and uber-powerfull ...
i remplace it by "universal turret" + "IncendiaryMunitions" +" napal artillery"

the new weapons are good, but their damage is just unsuitable, while a creature averages 300PV and 50 dmg, what's the point of having weapons that are 2k-2k5 dmg and 2k HP wall or just invulnerable (autoregen wall) non-logical technology tree (pomegranate higt EX before frag pomegranate.)
maybe on PVP server ...

If you are playing with the standard biters then this mod is not needed as the vanilla weapons are more than capable of removing the biter threat entirely.

What is 300PV?

Not sure what this means, non-logical technology tree (pomegranate higt EX before frag pomegranate.)?

The Rampant Arsenal is meant to play against the Rampant enemies mod. Wait until you get to 98% evolution and an ending evolution level of 10, and a damage/hit point scaler of 3. You won't think it is OP then. Same goes for playing with Natural Evolution Enemies.

Veden, PV means "HP" ,and "pomegranate" means hand grenade. lol. they must be french or italian or something?

french
