ZombiU

- Keep a decent gun in your safehouse, along with a few medkits and grenades. You will die, but it's not the end. While you lose everything that survivor had, so long as you can get back to where you died alive and well, you can kill the newly-zombified guy you were just playing as and get all your shit back.

- I don't know if Zombi does what ZombiU did, but it should, occasionally you'll also run into the zombified versions of other player's survivors. Kill them and you'll score whatever they were carrying at the time. Your stuff can't be stolen out from under you by another player or anything like that, it's just a copy.

- Mid/late game you can find bigger BOB's (Bug-Out-Bags) that permanently increase your inventory. Even if you die, the next guy will still have the bigger bag.

- Upgrade the pistol ASAP. Survivors always start with one and it stays upgraded between Survivors. (I think all weapons do, in case you completely lose a gun and have to go find it again).
