acute stress mod removes 1/3 (was 1/2) of your energy zoom works with i and o now cell boss has double the chance to spilt on damage. After it splits, each daughter cell has the mother's reduced health new gun neutron bomb, persistent AoE damage (might still have issues sticking to objects properly) new mob neutron bomb stuns mobs
