I have a £10 Steam voucher. What should I spend it on?

You gotta buy BROFORCE.

It's basically Expendables in a video game. Metal Slug-like with destructible environment, online coop, fun local multiplayer, and a bunch of epic characters : Terminator, Robocop, John Matrix, Neo, Conan, Rambo, Judge Dredd, Chuck Norris, McGyver, etc....
