SF-HiSplitter is an arcade game released in 1979 by Nintendo. The game is the direct sequel to Space Fever, with minor enhancements to make it somewhat worthwhile. Like the game before it, SF-HiSplitter is infamous for its immense similarities with Space Invaders. However, the similarities have dwindled compared to Space Fever. For example, the oncoming invaders are now twice the size they were before. When shot, they will usually dispatch into two of their regular invader size, though occasionally they'll blow up without doing so. Despite their less menacing appearance, having two oncoming enemies is more dangerous then having one large one, since their fire will be doubled.
