From Omerta Wiki
Abbreviation of 'no porting wealth from one version of Omerta to another'
This is a simple rule which forbids the sending of action credits*, money, bullets, HP, anything to another version of Omerta - which is as true for game language versions (for example NL-Tr) as it is for iterative versions (for example 3.4 - 3.5).
The reason for this policy is that we don't think that being rich in 'the last life' should make your rich in the next life, too.
Since approx version 2.6 it has been forbidden to use even a partly used donate code in a subsequent iterative version or to send it to another language version.
