I never had this game in either of its original incarnations on the PC Engine and the Megadrive, but remember wanting it when I saw a review of it. I think the UK version either never existed or was ub3r-l@@k-r@re.
It’s Breakout with two bats and zombies, basically. And it is pretty good too, making use of the second screen to see further up the level as you progress. Graphics are pretty poor though – no improvement on the Megadrive version, really.
Got through the first World, and stopped there.
