Halo: Out With a Wimper

Halo: Out With a Whimper is a fan-made game that has been in development since 2010. It aims to that take Halo's 3D gameplay, and transport it into a 2D platformer. It's what many like to call a "demake." 


The game makers plan a full "story driven" campaign, the game's enjoyable Firefight mode, customisation and stat tracking. 


According to the developers, Halo: Out With a Whimper will be playable sometime this winter.
