i think that you can craft medkit or ammo in one of the crafting stations, which will help you kill it. but if you are too weak you may not be able to pass the first battles in chapter3. how much Fitness and Will do you have?
hmm.. it is a little low. but make a medkit in the green area and ammo in the circuit room and you should be able to kill it, and hopefully you will be ok next chapter.
