No Heroes Allowed!, known as Yūsha no Kuse ni Namaiki da: 3D (勇者のくせになまいきだ:3D) in Japan, is the third game from the series. It was developed by Acquire and published by Sony Computer Entertainment for the PlayStation Portable in 2010 in Japan both physically and digitally, and in 2011 worldwide digitally only.
The gameplay is the same as previous releases, with new features. One of the most prominent is the addition of water and aquatic monsters. Also, new pickaxes are available after collecting Dragon Orbs by tapping on them when they are dropped by dead heroes. Fossils have also been introduced, which pop up in random blocks around the stages. Another new feature is "Badman & Badmella", a multiplayer mode that is played between two PSP's that both have the game. In this mode, one player plays as the infamous Overlord Badman, while another plays as Badmella, his daughter.
