Finding great flash games is not as easy as it sounds. I found the game The Last Stand at the donation coder blog and was blown away by the gameplay. It looks like your typical shoot all incoming enemies type of games also known as base defender gamers. At second look it introduces several strategic elements that make every approach different. You have to defend your barricades against Zombies at night and search for better weapons and other survivors at daylight. The goal is to hold out as long as possible and hope that someday a rescue team will come and get you out of this situation.
