LUO YAN, Bai Ze, Eclipse, and Rowan were all on one side of the floor while the remaining others were on the opposite side. They all decided to do a tower defense game first. Before the training started, there's a 10 minute break first so they could talk about strategy.
Tower defense was a sub-genre of strategy games where the goal was to defend a player's territories or possessions by obstructing the enemy attackers or by stopping enemies by reaching the exits, usually achieved by placing defensive structures on or along their path of attack. A common example of this kind of game was Plants vs Zombies.
Arcadia Cup's tower defense had a fairly similar concept.
The one that would represent the 'tower' was a huge crystal. If a team's crystal was destroyed, then the opposing team would automatically win. Participants of each team could also put defensive structures to protect their crystals. The problem was that, the players should activate it by themselves.
