The latest developer diary has been published on the Ship of Heroes site. In this new article, the team goes into detail to show off the process behind changes and upgrades to the male models in the game. Two models are spotlighted, one very muscular, the other "fit". Using these two models, most male NPCs in the game are created.
The changes were made at this time since all clothing and costumes will need upgrading as well to fit the new models. In addition, the body frame more accurately suits the "distinct action hero flair".
