Now, don't get too excited as this is unofficial and only one level, but... some clever developers have managed to get a proof-of-concept version of PC favourite Portal running on Android hardware.
The early work has been put together using the third-party Unity development software, which gives coders easy access to 3D programming tools on Android. It's a little bit broken and lacking in content, but it's still clearly Portal running on a phone and therefore rather an awesome piece of work.
In our dreams, Valve sees this, buys it, sticks all the maps in and has it on the Android Market for 69p by the middle of March. But in reality, it's likely to stay an unofficial fan project you have to seek out yourself. [Android Police]
