Restructuring and Updated Fifth Node

Restructured Critical Node

Critical Node of Shiyu Defense updated their stage structure in Version 2.5, reducing the frontiers from 7 to 5.

In this new Critical Node mode, the Fifth Frontier is upgraded. In order to gain higher rankings, Proxies will now have to defeat waves upon waves of enemies as fast and as much as possible, which means a high DMG output is key to winning.

The Upgraded Fifth Frontier

Restructured Critical Node Fifth Frontier

In the upgraded Fifth Frontier, Proxies will be required to complete 3 different stages, each with their own unique enemy lineups and bosses.

The new scoring parameter is based on DMG dealt, so having a higher DMG output is your key to a higher ranking. The higher your DMG output, the faster you can annihilate waves of enemies. The more waves you defeat, the higher your score will be.
