Inspired by the likes of Contra and Metal Slug, Commando 2 is a side-scrolling platform shooter with incredibly gorgeous pixel art and a surprisingly fluid control scheme. Choose an inventory of weapons randing from a sword to guns and explosives, then head out into the jungle and tackle enemies. The action is a bit slow and simple at the start, so veterans may need a comfy pillow in order to survive the lull stage.
