Badass Buspass Impasse is a TimeSplitters 2 Challenge. It involves going through the Streets level and picking up a brain and returning to the start. Much like the style of the TimeSplitters 1 Story levels.

Briefing

Badass Cyborg is having one of those days. First of all he loses his buspass and now he's realised that his spare brain is on the other side of town. It's not going to be easy going to get it back on foot. Especially when Special Forces have been deployed...again!
