[TAS] DS Contra 4 "all levels" by Soig in  

This is a tool-assisted speedrun. For more information, see tasvideos.org/3.... TAS originally published on 2019-07-19.
Contra 4 (2007) is largely a combined remake of the early NES and SNES Contra (tasvideos.org/S...) titles, featuring remixed music and vastly improved visuals utilizing both screens of the DS as if they were one contiguous screen.
Soig improves upon the previous publication (tasvideos.org/1...) by not only optimising it further, but also playing through the 40 missions of the game's challenge mode, which are unlocked after the main game is beaten.
