Ah, the expansion pack. Time was, you would rush out to your local game emporium to pick up an extra chunk of your favourite game, only to find you'd bought a couple of poorly-executed extra missions and a single new character/weapon/background texture. Thankfully, these days we ask for a little bit more for our hard-earned cash. Relic have been excelling themselves of late, not only producing varied expansion packs for Dawn of War, but also making them stand-alone so that any gamer new to the series can get stuck in, without having to shell out for the original. So, how does Company of Heroes:Opposing Fronts (or COH:OF as I shall lazily call it) stack up?
