Dual-wield

It is possible to increase your firepower by wielding two weapons, however it should be noted that two-handed weapons will incur an (unknown) [accuracy] penalty, according to Roger Wong's Gamespot Guide. The [Lawpistol], [Plasma Gun] and [Toxigun] do not incur any accuracy penalty when dual-wielded. Technically, the [launchers] incur a penalty, but since missiles are guided they don't make use of the unit's accuracy. Same goes for the [power sword] too due to its proximity requirements.
