NEEDS A SEQUEL-PART 5 name like sas5 zombie retaliation or something with even better graphics and add a lobby and better network stability control and survival in multiplayer not just as events and add different parts to collect for a weapon instead of crafting using alloys,and make a feature were you can pick up a players weapon if he or she dies but with limited ammo when you ran out of ammo,that would be cool,tnx.
