Next year to celebrate the 5th anniversary of pr2 there should be some sort of special update.
here are my ideas.
1: every server will always have happy hour activated.
2: A new hat should be released, in my head came the Army helmet: It gives you double ammo for all weapons, (6 laser gun shots, two mines etc.)
3: People that have been banned for eternity (five years) in 2008 are allowed back on and they get a welcome back!!! banner.
4: all levels will have a fireworks display in the background.
