Thystonius: Did you have a particular map in mind. While there are several players much better than myself, I have never taken over 20 minutes to link all 3 totems. Do you move Odin City or leave it in its starting place? Do you attempt to cap off all emitters before linking the totems? Many maps can be shortened in time by placing Odin City directly in the creeper to connect to a final totem which seems out of normal reach. Good luck.
Enderdragon99: It is my understanding that indefinite survival is impossible due to the limited energy creation capping at 32, while the creeper always increases. I will applaud your "success" when you show us a screenshot with some incredible time (something above 300 should do it). Thanks.
