Corruption, murder, betrayal, conspiracy...and that's just the opening sequence. As a 12 year old boy you watch your father (a navy 'Criminal Investigation Division' officer) and mother murdered. Growing up a juvenile deliquent you finally get released to freedom at age 18. Mayhem, revenge and retribution are on the cards as you set about avenging your parents the only way you know how.
Hire and train a crew or go it alone...take on a marine corps camp, drug lords' compound, kidnap an influential figure, assassinate a target for money. Build wealth and influence, mass an arsenal, command ships, all in the name of Retribution.
