Eurogamer writes: Old fashioned shoot-'em-ups are a lot like jazz. Once a driving force of pop culture, both are now savoured only by a dwindling number of dedicated purists who grumble at how the bovine mainstream masses are incapable of appreciating the off-kilter appeal of their chosen obsession. In years gone by games like Xevious and R-Type were legitimate blockbusters, accessible to anyone who had a pocketful of change. Today's vertical and horizontal shooters are obscure, chasing the remaining faithful, wallowing in their hardcore status and pulling scary faces at any normal folk who happen to glance in their direction.
Which brings us to Triggerheart Exelica, which pulls a very scary face indeed. Released into Japanese arcades in 2006, it holds the honour of being one of those games still being ported to the Dreamcast - and the Dreamcast alone - many years after SEGA's white brick of loveliness was supposed to have rolled over and died. Much like Rez, that other Dreamcast shooter that tore its way back into our timeline via Xbox Live Arcade, Triggerheart is a game of short length but deceptive depth.
