You could change things up a bit and include some S's or whatever to be the scientists fleeing for their lives, and so you don't want to shoot them, but the X's (monsters) will move toward the scientists since they want some revenge for all the experiments done to them, so not only are you trying to prevent the creatures from escaping the perimiter you set up, but you are also trying to rescue the fleeing scientists and you get bonus points for every scientist that makes it past your perimiter without being eaten by a monster...
