you could add hydras to LW, but make it impossible to shoot with them.
that things are pretty awesome for stunting.
i guess if you disable the weapons its alright to add them to area 69 as a normal vehicle.
im sure you guys are not stupid enough to add them fully armed. those things got EPIC weaping range, epic handling, epic fire rate, epic everything. it doesnt matter if they have 500 health points or 1000.
and gryphus: nobody will be so stupid to give you the possiblity to get a fully armed hydra on lw.
