landgreen a7ad085deb neutron bomb 
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
