For someone who doesn't know, here is how you would play. After 40 people joined, the server would put 10 people on each team. The teams were: Team 1 (Island), Team 2 (Mountain), Team 3 (Jungle), and Team 4 (Ice). You had 15 minutes to gather materials. After 15 minutes, the walls separating the teams would disappear. To punish camping in your team's corner, there were 14 diamonds in the middle of the map. (Diamonds could not be found anywhere else). This encouraged players to be aggressive. Once you died, there was no respawning. Once all 10 members of your team died, your team was eliminated. The last team standing won. Seems simple enough, but crazy strategies were born out of this. The most notable was called "skybasing". Which was building up hundreds of blocks and making a bunker. It was hard to attack, even with the materials from the middle of the map. If you Google "MCTheWalls Tournament" you can find some of the tournaments that happened every few months.
