Mount Your Friends is apparently a bit like QWOP with large swinging dongs. If that doesn’t entice you to play it, I don’t know what will.
To put it another way, Mount Your Friends is a competitive physics-based game in which players take it in turns to climb a tower of men, in an attempt to become the new highest point. If they don’t make it to the top then they’re eliminated, but either way it’s then the turn of the next person, who attempts to climb even higher. Also, the men appear to be wearing nothing but thongs. Thongs which barely hide their pendulous, physics-enabled dongs. So yeah.
If this sounds like your sort of thing – and why wouldn’t it? – you can pick up Mount Your Friends on Steam for £3.19. It’s usually priced at £3.99, but hey, it’s got a 20% launch discount.
