Rock of Ages 2: Bigger & Boulder is a tower defense game, available on Play Station 4, developed by ACE Team. The game is based on the concept of giant rocks rolling through historical and artistic ages. The game is back with improved graphics, physics, and destructibility powered by Unreal Engine 4.

The game has an emphasis on chaotic multiplayer for up to four rock-rollers, new time periods, and improved graphics, physics, and destructibility. Players can customize banners and colors for their units and engage in local split-screen or up to four players online in a 2v2 match to the death. Opposing tracks can now intersect each other, adding to the gameplay's excitement. The game has an absurd art style inspired by the greatest art periods in history, and players will encounter historically inaccurate bosses featuring the likes of The Thinker and the Great Sphinx.
