It depends. Some mods do as little as simply making Zero Hour's Leang playable. NProject adds bug fixes and small gameplay improvements. Other mods like Shockwave and Operation Firestorm completely changes Leang's arsenal into something more unique and original. Shockwave!Leang shifts away from brute force in favor of artillery, advanced fire weapons and tectonic weaponry—which requires tactical usage. OFS!Leang focuses more on digital advancements with EMP, ECM and her take on vehicle drones. And those are a few mods out of many with their own unique takes on Leang.

Don't mind me, I'm just covertly making a mod. No further progress until major progress is done.
