ACE3 and ACEX

1. ACE3

ACE3 is a joint effort by the teams behind ACE2, AGM and CSE to improve the realism and authenticity of Arma 3.

It provides many features which enhance realism gameplay, and provides frameworks which mission makers, modders and scripters can use to enhance their own missions and mods.

2. ACEX

ACEX was an optional package of mods that complimented the ACE3 modification.

ACEX was merged into ACE3 v3.14.0! Remove it if you still have it installed.
