1. clan trick.
2. join the crowd in killing cubikon. you will earn maybe 70k-100k credits in 30 seconds..
3.only kill kristallon when you have atleast 2k laser damage.
4. (most effective) bid on slot cpu 2,3 and 4 and aim 01 cpu..open auction in 4 tabs.. on the first tab bid on slot cpu 2 put 50k credits but dont click bid yet, 2nd tab 360k credits on slot 3 on tab 3- slot 4, 870k credits. on tab 4- aim01.120k credits...only click bid on each of the tab when there's 30 seconds left..5 seconds gap on each click..be sure to always overbid the current bid..sell all cpu's you got after 1 week..i make 50 million credits from this before.
5. get the cubi's cargo.. most effective when you have pet auto looter and cargo trader gears..
6. (the best)use a pixelbot and forgot about playing d.o. it's not worth wasting your time to this game.. spend your time exercising while botting.. i recommend you to use vbotfree or boxybotpb.. if you want some palladium use pala by palavia or vbot palla...
if you think you can be pro by playing the game without spending money then your wrong...even thou it's not impossible but spending a portion of your life for a game is not worth at all..so use bot you can get 50k uridium a day with vbotfree or boxybotpb.
