Halloween Harry/Alien Carnage. The year 1993 is quite a lucrative year for Apogee: besides big hitters such as Duke Nukem II, less popular platformers including Alien Carnage also make make an entry. Or should I say Halloween Harry? The confusing title suggesting a Halloween theme was ditched in favour of Alien Carnage a year later. Apogee probably hoped to increase sales that way and also introduced its well-known shareware tactic: release two of the four episodes for free. Via Jefklak's Codex
