Unashamedly inspired by SNES classic Super Metroid, this brought the HD era back to its 2D roots in spectacular fashion. The variety of weapons, abilities, and upgrades in this game (plus subterraneous scumbags to try them all out on) makes this the best side-scroller since, well, Super Metroid.

YOU AUGHTA KNOW:
In the beginning of Shadow Complex's four-year development cycle, developer Chair mapped the entire game out on graph paper and played it out to make sure everything worked. Analog style, FTW.
