"Q: Can I take three of the same (not Twin-linked) weapons on my
Crisis suit? (p100)
A: Yes. Rememberthough that a Crisis battlesuit can still only
fire a maximum of two weapon systems per Shooting phase.
For example: A Crisis battlesuit could be equipped with three
(non Twin-linked) burst cannons, or one Twin-linked burst
cannon and one (non Twin-linked) burst cannon, so long as
you pay the appropriate cost in each instance. In either case,
make sure your opponent is aware how you have chosen to
equip such models at the beginning of the game."
