There's an old game I used to have for mac. It was a first person fighting type game where it pits you against other cpu competitors. You chose a character, and each one had a special weapon. I remember once character had like a giant baby head. While battling the cpu, you also had to collect certain items. The arenas were maze-like, and I recall one of the arenas being called the Topiary. Any help would be fantastic! Thanks!
