Ecks vs. Sever is a first-person shooter developed by Crawfish Interactive for the Game Boy Advance, released in 2001. At the outset, players select one of two characters — Ecks or Sever — each following an interconnected narrative through a distinct set of mission levels. The two storylines unfold in parallel, offering different stage designs depending on the chosen protagonist. Visually, the game employs a approach similar to early FPS titles like Doom, rendering enemies and weapons as 2D sprites within a three-dimensional environment. The combination of dual campaign paths and sprite-based graphics represented a notable technical effort for the handheld platform, bringing a style of gameplay more commonly associated with home and PC systems to the Game Boy Advance's limited hardware.
