The Expendabros is free on Steam

Some Expendables themed missions have landed for Free Lives lovely action-platform game, Broforce. The new content is completely free-to-play and can be downloaded now on Steam. Here's the blurb, incase you need further persuasion:

The Expendabros have assembled and set their sights on the forces of ruthless arms dealer Conrad Stonebanks in the forests of Eastern Europe. Battle through ten full-throttle missions set amongst the picturesque tree tops and the absurdly dangerous lumber mills teeming with enemy soldiers, excessive artillery, and inconveniently placed circular saws. Rescue your brothers in arms and play as seven different legendary soldiers - each with their own unique weapons and special attacks - with up to four players at once in local multiplayer co-op mode.
