Missing key item in chapter 2

[no try hard team]

Before i enter the train rush map, the game say that "I miss a key item. Do you wish to continue anyway?"

You'll find the item you need in Chapter 3 act 2

[no try hard team]

thank you

If you're a true pro you can finish the act without the item

[Vasheeri]

the game literally wont let you progress without it...don't know why they even let you go in that level without the item.

(unlike the race mafia level, where it is still possible to beat it without the item.)
