Hard Corps: Uprising [NPEB00332]

[Ru4slan]

Now there're 2 problems: one is that if I choose the DLC characters such as Leviathan or Sayuri (I don't like Harley Daniels at all because he is too slow)the game will get crash at stage 4; the other is the final stage is too slow, although it shows 55fps I do feel it is only 30fps which is too hard to play.

30 FPS is too hard?
i defeat first mini-boss(first stage) with 5-8 FPS.
