The crew at NeoGaf created this LittleBigPlanet stage. Here's the youtube write up:
LittleBig Contra is a NeoGAF collaborative project aimed at delivering the definitive Contra experience to LittleBigPlanet. Our goal was to recreate each of the 8 stages of Contra from the NES using the tools available to us in the LittleBigPlanet level editor.
There are 8 stages in total and 7 authors on the LBC team:
Stage 1: Jungle: PSN - Leonidas2123
Stage 2: Base 1: PSN - SaitoHalifax
Stage 3: Waterfall: PSN - RyanardoDavinci
Stage 4: Base 2: PSN - SaitoHalifax
Stage 5: Snowfield: PSN - NinjaMicWZ
Stage 6: Energy Zone: PSN - El_Beefo
Stage 7: Hangar: PSN - Jaeyden
Stage 8: Alien's Lair: PSN - gevurah22
Maybe they can tackle Super Mario Brothers next?
