Base Capture is the 3rd and last mode that is actually implemented in the game, the goal is to take and hold a set number of base. to take a base you must stay on a small circle for about 10 seconds without moving out of it. whenever a team has all the bases they win the game by killing all champions of the enemy team (if your team has no bases you don't respawn after death) or by holding these bases for about a minute.
I'll add a video of the mode tomorrow, today was quite though and i'm to tired to play and record myself. sorry guys.
