In the end you've got to blow everything up... even yourself. Everything looks very green, but it's not night vision; it's hero vision. The two types of vision are often confused, but if you'd bothered to play through the whole game we promise you'd understand (maybe).
At the end of the video it's a bit unclear whether or not you survived the explosion, but we can say indefinitely that you probably did survive because we like happy endings more. Congratulations soldier, you've just watched the end of GRAW2 without having to play through the game.
