Im a returning player from 2014, back is those old days i could get pvp ( solo) video content by a section in this forum where players posted their pvp gameplay. where is this now? or is solo dead? where do the best playhers ingame post their content now?
It’s probably worth checking out the eve wiki on it in case I get some details wrong, but in very general terms the ESS is basically a site in null systems that is a bank, and collects part of the money obtained by ratting in that system. Other players can steal from the bank, either by just linking to the ESS for some of the money, or using an actual key for a lot more money. When you link to the ESS it sends out a notification so everyone knows you are robbing it. The ESS itself is a dead zone that requires a gate, and you can not cloak in it, use an MWD, light a cyno, or warp out of it. So people use very specific fits to rob it, then engage the locals as they come to defend it.
You might want to check out videos by BjornBee and Grunt Kado who both have some very good ESS fights. Kado in particular flies a multitude of ships in them.
