Grimlore Games have released a mod kit for their latest title SpellForce 3. The tools are the same used by the developers and have an extensive scripting tool making it possible to not only create maps but also custom missions.
SpellForce 3 was released back in December receiving mixed reviews on Steam being criticised for it’s $49.99 price tag and a handful of bugs. The game takes place before the original SpellForce and mixes the RPG and RTS genre to create a detail-rich game with plenty of strategical elements for RTS newbies and veterans alike.
