Jungle based mini game
We have nexus seige which is just a crazy version of the ending of a normal game. So why not a jungle based mini game on summoners rift. Only one lane, mid lane, all the jungle is there though, except at dragon and baron pit there are bigger and stronger version of jungle camps, and each time both dragon and baron camps are clear a gaint red and blue buff appear, and after that 2 dragons, and two more dragons then one epic elder dragons as the final boss of the game went that long. So here is an example of how this mini game would work, there is a single giant gromp in baron and dragon pit, the team has to clear half of their half of the jungle to fight the giant gromp, so to fight the gromp at dragon pit and you are on blue side, your team needs to kill raptors, red buff, and krugs then you can step into the dragon pit to kill the giant gromp. Killing the monster in dragon or baron pit takes away 1 point from the enemy nexus, after your team kills a gaint gromp, and then a giant red buff, then a dragon which is worth 2 points, then a second dragon worth 2 points, then a final and single epic elder dragon worth 3 points, but your team has to clear all of their jungle fiest before they can fight the final dragon. Each team nexus has 9 points. Feel free to ask any questions if some parts are confusing to understand
