Massive Assault: Phantom Renaissance features a renewed global conflict, starting five years after the First War for the New Worlds ended in Free Nations Union's victory. The remnants of the defeated Phantom League go underground, preserving a couple of undisclosed Secret Allies with hidden research facilities. New types of unprecedently powerful weapons have been developed. They commence their surprise attack during the celebration of the Anniversary of the Great Victory, destroying more than half of the F.N.U. forces on the parades - then they easily overtake all major cities driving the remaining F.N.U. detachments to mountains and islands and to some yet unpopulated planets.

Massive Assault: Phantom Renaissance will include all-new "Assault" mode, where a player will be given limited resources to recruit and deploy a task force and capture a network of well-guarded enemy strongholds, taking key positions within established turn limit. This mode will add one more exciting strategic level to Massive Assault's gameplay - huge face-to-face battles similar to those of ancient and medieval times.

Other additions and improvements will include:

* 6 new planets for World Wars including massive-sized deathmatch maps
* 2 Mega Campaigns featuring various warfare styles: prevailing defensive operations for F.N.U. and offensive tasks for Phantom League. Mega Campaigns will also include World War and "Assault" mode steps.
