A Roman Cancel is a feature unique to the Guilty Gear franchise. It enables you to pull off more complex combos more easily, at the cost of half of your Tension meter. By default, this is activated by pressing three face buttons down at once, but you can also re-map this function to any of the remaining buttons on your controller to make it easier. Try and do at least one in any match you can and you'll have this in no time, but there is a trick if you find yourself needing to grind these out. Survival Mode offers several easy, one-round matches in a row, and generally your Tension meter will be charged at least halfway by the end of one. This can let you get ten or twenty Roman Cancels in just a few minutes. These do not all have to be done in a single match, and can be done online, with CPUs, or locally with two controllers.
