I upgraded an early FarCry and released in on crymods.net in 2015. I have combined it into a single file to release as a MOD here at moddb.
Jack Carver is marooned when his fishing boat hits a reef and sinks. He fights his way across a group of islands against mercenary soldiers and other strange creatures. He eventually reaches a medieval castle, the headquarters of a Colonel Crowe. Jack kills Crowe and escapes in Crowe's gunship.
