The Invasio Barbarorum team have released a mini campaign for kingdoms:

It starts in 429AD and the map focuses on the Western Mediterranean. The mod contains 5 factions - The Western Empire, The Visigoths, The Vandals, The Berbers and The Suebi.
I think its a major step for the community - I know its late Roman rather than Classical Roman but its still great to play as the Romans using the M2TW version (I played an earlier BETA a week or two ago). I think Ramon and the rest of the Invasio Barbarorum II team deserve a round of applause.
3 more campaigns are going to be released this year followed by a Grand Campaign - Essentially the main IB1 mod but for M2TW Kingdoms. I think Paeninsula Italica is a few months off releasing its M2TW engine so relatively soon we will be able to play as Rome in the 4th century BC and probably in a year or two EB II will be released.
