Shadow Complex uses a 2.5D design, with the player moving about levels like a side-scrolling video game but required to dispatch enemies in three dimensions.

Metroidvania is a sub-genre of action-adventure games and/or platformers focused on guided non-linearity and utility-gated exploration and progression. The term is a portmanteau of the names of the video game series Metroid and Castlevania, based on the template from Metroid (1986), Castlevania II (1987), Super Metroid (1994), and Castlevania: Symphony of the Night (1997).

In Guacamelee!, the player gains the ability to temporarily turn their human character into a chicken, allowing them to pass through low-height corridors and discover secrets.
