Easy 5,000 Uridium
This is the cheapest way of buying your uridium, it just costs your normal text rate on mobile. It took me three tries and so I recieved 15,000 uridium. Send BIG 2498957 to 84212, If it does not work retry or maybe you put the wrong code, NB: there is 'space' between 'BIG' and '2498957'. Do a maximum of Three Tries, Trust me now Im a Goliath user now with so many Iris drones. Happy new year and Christmas to who ever enjoys this cheap Uridium.
There are hidden maps on dark orbit. to find them, follow this guide. Do not do this unless you have a bigboy, a vengence or goliath.
First of all go to map x-4. You will find a jumpgate in between two other ones. Go through it. Next, go to the center jumpgate. (you will find that you can not see it on the map that pops up after you jump) go through it. You are in a secret map! Explore but beware! the jumpgates do not offer protection!
