If there’s one thing I love, its creative mod-videos. Well, buckle up for one of the most popular level mods of all time (Little Big Planet especially): Contra’s first level.
In my opinion, 3D mods for 2D games put a whole new spin on retro titles: the creator has to interpret everything that isn’t viewable on a 2D plane, as well as figure out a way to incorporate the parent game’s mechanics as seamlessly as possible. Obviously Contra is perfectly suited for a parent game like Half Life 2. If you enjoyed the video, the author, m0rtanius, also has Half-LifeVania and Super Half-Life Bros. for your viewing pleasure.
