Killing foreign-looking things with bombs – not really that acceptable most of the time, but apparently it's the most normal thing in the world for Roly-Poly Cannon 2.
You might remember the original Roly-Poly Cannon, where you had to destroy a number of spherical enemies by blasting them with a cannon in a number of tricky physics-filled levels. Well Roly-Poly Cannon 2 is exactly the same as that, except this time a) some of the baddies are dressed as stereotypical foreigners and b) there are hostages who you can't kill. It's sort of like a spherical 24, really.
