Megaton Rainfall [official site] is a very promising-looking indie title. Oh my, does it look promising. I hope it delivers on its promise, I really do.
This is why: you play as a superhero, flying at high speed around enormous cities packed with skyscrapers and tiny people, defeating the aliens who are attempting to destroy every human construction in sight.
The teaser trailer spends much of its time focused on the aliens ravaging the city (take a leaf out of EDF's book and call them "Ravagers"), so I suspect I'm not alone in wanting to watch the destruction rather than prevent it. Or at least let a little destruction happen, but then step in before things get out of hand. I particularly love the alien weapon that peels a skyscraper like a banana. Most cool.
There's little focus in this trailer on the playable character, and when we do see that there's little trace of what the gameplay will be like - so between that and the dearth of other information available it's probably too early unqualified excitement. But I can't help it. Skyscraper! Banana!
Megaton Rainfall is being developed by Alfonso del Cerro, a Spanish dev who went full-time indie (as Pentadimensional Games) in order to see this game to fruition. He's demoing it at GDC next weekend, so I suspect that if it's any good we'll be hearing a lot more about it fairly soon.
(A small aside: I'm not sure that anyone has ever made a first-person flying superhero game before. There was that cancelled THQ Avengers game, but that's all I can think of. Huh. It seems like such an obvious concept for someone to have done, doesn't it?)
