Defeat the Five Tiger Generals (Guan Yu, Zhang Fei, Zhao Yun, Huang Zhong, Ma Chao).
Keep all or most Tiger Tanks safe.
Do not move too ahead of the tiger tanks, because enemy attack troops
will appear and attack the tiger tanks if you are too far away, and
sometimes close up gates behind you and block you from them, preventing you
from going back to rescue them.
Move slowly, this is a 60 minute stage, and a weapon that doesn't have a
time limit to unlock. So just walk alongside the tiger tanks and move with
the same pace as them.
