Really, its all about weapons and armor upgrades. With armor, agility is your best friend. You will need to get out of dodge quite a bit and on morbid, strength will not help you. With weapons, it depends on your playing style, but I didn't even bother buying the SMG. The three weapons I focused on were the shotgun, the shocker and the launcher while falling back on the rifle. The shocker is useless unless its power and range are fully upgraded so do that with time. You will also want to maximize your flares and mines as soon as possible. Also, go slow and don't rush into things. Always have a game plan on how you want to dispatch the next batch of enemies.
