LittleBigPlanet 2 levels work best when they stick to platforming conventions but throw in a bit of innovation too. Like this one, based on the Killzone series and whilst still a 2D platformer it riffs on the best bits of Guerrilla’s shooters and features some familiar enemies.
The intro alone is worth the play, but stick with the level until the end for a cool boss battle. Great use of cut-scenes and some clever elements make a short but impressive level.
There’s also this one, from Kevin Middelbos, which plays a little bit like Doodle Jump but with Killzone characters!
