343 * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.

345 * required to make each shot, spreading the shots out over time.
346 * Note that when firing missiles, the launcher multiplier is applied
347 * after all the bonuses are added in, making multipliers very useful.

349 * for the damage multiplier.
