No, the feature was never finished and was dropped from the release, especially after team members started to drop out.
I do not recall the exact details since I left years before the eventual release (worked mostly on missions, including all the Multiplayer Maps) but there was a lot of friction regarding the codebase. WCS is based on an OpenSource Freespace 2 Engine (see here
) and at some point the devs were implementing features left and right for total conversions like WCS before that slowed down for some reason.
I was not involved in the actual decision making there but I vaguely remember a lot of complaining from both sides. WCS eventually branched off and did its own thing but that code base then stagnated. This is why the release of WCS ran on an outdated engine-version compared to what OpenFS was on at that time.
Whole features were dropped later, like Multiplayer, which was both unstable and not-performant enough (an issue only recently tackled by the engine) and features that the WCS team was hoping to obtain never materialized. TA lot of WC3-style things were planned, including cockpits and taunting, but fell victim to those difficulties.
Kudos to the (two?) brave final members of the WCS team who pushed this thing over the finish line. Yes, the release certainly had problems and a few missions were borderline ridiculous but they managed to release a really big, totally free, fully voice-acted video game and that deserves respect.
