[fabianhidalgo]

sh4 will be compatible with sh3 ?

[Pants]

no it wont be...it's the same engine however, but extremely modified

[Onkel Neal]

no.

Txema, 32, Spain: Could you make SH4 compatible with SH3 in such a way that the engine improvements introduced in SH4 could be used in the SH3 campaign and missions?
SH4 Dev Team: The engine of SH3 is not compatible with improvements from SH4. There are parts in SH4 that needed to be rewritten in order to improve and add some game play aspects
