Pioneers will be a turn-based game with RPG elements. It's a game where you start by assembling your exploration party with men with different abilities and skills. Every man counts and every skill counts. You need someone who's good with weapons and hunting, someone who is good with carpentry, someone who can draw maps, someone who could easily learn native languages and so on. Once that's done, you put them on a ship and head for some unknown land.
Build 5 features a simple tutorial mode along with an even simpler intro sequence, introduction to a story of sorts plus a lot of fixes and improvements along with new developments like heightmaps, new campsite and ship screens, Lua support for quests, a couple of new tunes, a new UI style for windows and buttons and a lot more.
