Way back in the mists of time, when the Spectrum was the machine to own, Ultimate produced a game called Atic Atac for it. For its time it was a superb bit of programming. Now it makes an unofficial return in the form of Creepy. In fact, Creepy is an absolutely unashamed clone of Atic Atac. It's a shoot-'em-up viewed from above and involves rushing about a castle, shooting and avoiding the monsters, grabbing food and other weapons whenever you can get them and sometimes visiting the shop, where you can buy more weapons, helpful potions and extra energy.
For a STOS-written game, Creepy has fair graphics and gameplay. If you've played Atic Atac you're played Creepy, though if anything the original game is actually a little better. That's either a testament to Ultimate's programming skill or an indictment of Creepy. You decide.
