The Cracked Door appears in City, Outpost, and Docks (however, the docks cracked door is gray to fit the wall theme). It is an event in Build Mode and requires the Dynamite (City or Build Mode) or a Tank Bullet (Outpost) to blow it up, more preferably open it, depending on the map.
It also is an invisible event in Plant - Chapter 12 during the RB Battles 3 Event. It reveals an area formerly inaccessible, containing the Symbol Code Safe.

Trivia[]
- This is the only door that can be opened with two different items (Tank Bullet and Dynamite).
