Developer Twisted Pixel has released some really solid games on Xbox Live Arcade over the past few years, and a bundle was announced this week that nets them all together digitally. The bundled games include The Maw, Splosion Man, Ms. Splosion Man, and Comic Jumper.
There's currently no release date or price, but the games will be discounted from their solo total. Either way, if you don't have any of these already, this is definitely a solid package to look out for. Twisted Pixel's games are pretty great, especially the Splosion Man series.
