For the [[AoS/Soma_Any%25 | Any%]] and [[AoS/Soma_All_Bosses | All Bosses]] categories where gaining XP early on 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 two Zombies which always spawn there. An earlier throw will kill one Zombie, whereas a later throw will kill both Zombies. Too late of a throw will miss both.
