There’s always an element of risk involved when attempting to mix genres. Add too much or too little of one or the other and players will question why the attempt was made in the first place. Select the wrong elements and the experience is doomed to feeling clunky at best and downright irritating at worst. Choosing the correct pieces and getting the mix just right, however, will yield a product that feels so natural that players will wonder why no one else had thought of it before. Such is the case for Null Vector, a surprisingly successful fusion of twin-stick shooter and roguelike.
