How do the biochemical soldiers of the creative corps play the expedition mode?

Expedition green crossbows and blue crossbows can improve your output. It is best not to use spray or grenades for expedition purple crossbows. These two weapons can't attack boss, or their accuracy is low.

The higher the weapon is strengthened, the higher the output.

These weapons can be obtained in the task king gift box or the expedition mode clearance flop.

Hope to adopt-thank you.
