It's a PvP game that revolves around tactic, teamplay, careful planning and good reflexes. Each player controls 1 of over 100 unique champions. 2 teams of 5 players are trying to destroy the other team's base. Each team's base sends out waves of minions over three lanes. This is the map: [link] It might be a little out of date but the essentials are still the same. How to win a game: Destroy the enemy's Nexus. Before you can do that, you have to destroy the 2 heavy towers in front of it Before you can do that, you have to destroy one of the 3 Inhibitors. Once an Inhibitor is destroyed, the base spawns a really heavy minion with every wave that goes on the destroyed Inhibitiors lane. But before you can destroy any Inhibitor, you have to destroy the 3 Towers before them. And you have to destroy the towers in order too.

Finally!! someone who agrees with me on He-Man being the best when he was just a Barbarian. I loved the figures and collected them when they came out, it was just a cool scifi Barbarian story, and I was excited to hear about the cartoon, but when it came out, my jaw dropped with the opening because of that "By the Power" Prince Adam nonsense. I just didn't care for that show.
I just loved the original, and sadly so few realize that He-Man was so much cooler before that cartoon. Plus I know what you mean about the figures. I miss mine so much as well.
