RuneScape Zombie Apocalypse

A friend of mine posted this on Tumblr. It was a bit of fun, so I thought I might share it here, too. Have a think and post your replies. Should be interesting
Here's the scenario:

Runescape is now real life and zombies have taken over.

• The last person you spoke to on RS through your private chat, and the last NPC that you spoke to, are your two team mates. And yes, bots that spammed your PM do count.
  
• The last place you teleported to is where you’ll spawn.
  
• Your current equipped gear is what you have to defend yourself with.
  
• The first 3 items in your bank are what you can use to your advantage.
  
• You have no food, but full prayer.
  

How long will you survive, and what’s your plan?
