Related introduction to the "Girls' Frontline 2" game:

"Girls' Frontline 2: Chase" is a role-playing strategy game developed by Shanghai Sanbo Network Technology Co., Ltd. Open beta on December 21, 2023. In the game, players will act as commanders and lead a tactical humanoid team through the contaminated area, receiving and completing commissions while facing off against successive enemies. As the game progresses, various forces appear on the stage in turn, and the conspiracies brewing under the new order will gradually surface. The choice is once again before the players.

Although this game is a war chess game, the strategic difficulty is not high. It is difficult for players to see the performance differences between different characters. The process of each level during the battle is similar. Overall, it's a boring game. "Girls' Frontline 2: Chase" is as expressive as classic war chess games in terms of map structure and strategic depth. Overall, the work is more like an unfinished work in progress.
