ROC Defense is a mobile game in the tower defense genre. Players will have to go through level by level, exposing the anime fighters to individual cells. They will repel attacks from both regular units and giant dragons acting as bosses.
New characters are called to the battlefield in ROC Defense by mana, a resource that is gradually accumulated. In addition to heroes, players can use spells that inflict damage on the enemy or temporarily improve friendly fighters.
Players must collect a deck of rare cards, with the heroes also divided into elements. The boss is hit every 15 rounds, each of which requires a different strategy. Also, ROC Defense has world bosses, if anyone finds them, then everyone can join the fight; so it’s a local alternative to raids.
The developers of ROC Defense hint at the possibility of obtaining special items if you get a lot of points for the fight.
