After the disaster of the earthquake and tsunami in Japan, developers have been slashing prices on their games and donating the profits to relief efforts. PopCap is the latest to pitch in and is joining the movement by discounting its iPhone games to $0.99 and its iPad games to $1.99.

“We recently opened an office in Tokyo, and while our Japan-based employees are safe and uninjured, we understand countless others in Japan need food, shelter, and medical attention,” said Ellen Marett, Senior Director of Workforce Culture at PopCap. “Given that Plants vs. Zombies reached #1 on the iPhone and iPad sales charts in Japan, it seemed like the most appropriate game to feature in this fundraising campaign.”

PopCap is the developer of some of the most popular games on the iOS such as Plants vs Zombies, Bookworm, and Peggle. The campaign is only going to be running from March 19th to March 20th, so act fast.
