Publisher True Games Interactive has announced that it has joined forces with independent developer Petroglyph to create a free-to-play RTS that will be supported by micro-transactions.

“Petroglyph is known for high quality RTS games that appeal on a global level, and when combined with True Games’ expertise in the micro-transaction arena we have the recipe for an international blockbuster,” said True Games chief publishing officer Jeff Lujan.

Petroglyph, founded by ex-Westwood developers, is best known for Star Wars: Empire at War and most recently Universe at War: Earth Assault. The game will be supported through in-game items being sold at a low sum of actual currency.

This move marks the new trend of developers pursuing free-to-play titles. The most popular one is the forthcoming Battlefield Heroes by EA DICE, which will be supported by advertising and micro-transactions.
