per il RE5 è stato utilizzato la versione dell'engine 1.4
Although MT Framework is just now turning 2.0, it's actually been through a number of iterations. The first version was used for Dead Rising in 2006. This was followed by version 1.1 for Lost Planet, version 1.2 for the PC version of Lost Planet, version 1.3 for Devil May Cry 4, and version 1.4 for Resident Evil 5.
