OpenXcom is an open-source C++/SDL reimplementation of the classic strategy games X-COM: UFO Defense and X-COM: Terror From the Deep, requiring the original game resources. It fixes bugs and limitations of the original engine while adding extensive modding support.
Use cases
- play x-com ufo defense on modern systems without dosbox
- run terror from the deep natively on linux
- mod x-com with new rulesets and content
- fix original x-com bugs like item limits and funding overflows
- play classic x-com with community mods
- recreate the original x-com experience with a modern codebase
When to choose
- you own the original X-COM games and want to play them natively on modern OSes
- you want a bug-fixed, moddable version of classic X-COM
- you want to develop or install community mods for X-COM
When to avoid
- you want the most feature-rich modding platform - use OpenXcom Extended (OXCE) instead, which is the officially recommended successor
- you want a modern X-COM game like XCOM: Enemy Unknown (2012)
- you don't own a copy of the original game resources
