Announced recently, Melesta Games wants to help gamers celebrate the 4th of July. In honor of America’s birthday, five of the the developer’s most popular games (Rolling Idols: Lost City, Space Roadkill, Zuba!, Toy Defense, and Toy Defense 2) are now free for a limited time online. The offer lasts one week, running from July 1st and ending on the 7th.

Rolling Idols: Lost City HD is a strategic puzzle game set in the world of the ancient Mayans. Players must save the planet from an ancient evil called Nibiru to become the ultimate hero. Rolling Idols: Lost City HD is also free for a limited time. Zuba! is a casual arcade or “endless rolling” game in which players help a funny character named Zuba during an exciting chase for candies and sweets. Gameplay combines classic arcade elements with the unique capabilities of iOS.

Developed jointly with Disc Soft Ltd., Space Roadkill pits players against hordes of zombies, mutants and monsters on a distant planet. The only way for players to escape the infected planet and get home to Earth is by jumping into their cars and driving as fast as they can. Finally, Melesta Games‘ classic World War I strategy game, Toy Defense, is free on the App Store as well. The sequel, Toy Defense 2, is also free across and players take part in the most decisive battles of World War II — including Stalingrad, Normandy and Operation Crusader — re-imagined as tower defense levels.
