This is a speedrun by DraQu, the guy who spent some time on top of the Devil Daggers leaderboard. Unlike most speedruns I've watched he was streaming it live on Twitch, so you get his live commentary and emotional ups and downs, which is pretty great addition.

A speedrunner streaming on twitch? Impossible.

Into the Fire was a particularly cool segment to see. Using the Gauss Rifle to boost onto invisible walls, scaling the cliffs outside the level and then flying through the side of the tower into the teleport room all in about 30s is impressive. It's also nerve wracking because he's on invisible geometry and one slip means having the start the game over.

How the fuck do you find all those exploits. Game hasnt been out that long.
