Video: Smash Bros. adventure mode explained

Aliens and R.O.B the Robot wants to wreck Mario's world

As previously revealed, Super Smash Bros. Brawl will not just be a fighting game, but will also pack a fully-fledged adventure mode called the Subspace Emissary, but what's it all about?

The plot centres on a new enemy, The Ancient Minister, and his army of Primids who plan to suck the world into subspace using special subspace bombs. Petey Piranha (from Super Mario Sunshine) turns up and kidnaps both Princess Peach and Zelda, while two R.O.B the Robot units trigger a special subspace bomb. The aliens must have hacked the R.O.Bs though, because we refuse to believe that our spindle-lifting NES friend is evil.

The Ancient Minister enters

From there on the gameplay switches to side-scrolling action, with stages designed for each of the playable characters in the game.
