For the [[AoS/Soma_Any%25 | Any%]] and [[AoS/Soma_All_Bosses | All Bosses]] categories where it's important to gain extra gaining XP early on (Any% and All Bosses)is important, it can be useful to also throw a fourth spear when Soma's head touches the edge of the column in the background, potentially killing one or both extra two Zombies which always spawn there. An earlier throw will kill one Zombie, whereas a later throw will both Zombies. Too late of a throw will miss both.
