if you want to revive tremulous, migrate over to GPP. it makes no sense to propagate the "legacy version".
GPP has bugfixes by which some cause unliked gameplay elements for 1.1 users
i.e.
Pouncewhoring - Possible in 1.1, but so fucking overpowered in gpp.
Zapping - Requires skill in 1.1, it's a free long range headshot with a longer "reload" timer in gpp.
Turrets - GPP turrets are so easy to fool, due to how buggy the "spinup" was coded.
Healing - Although overpowered in 1.1, the tyrant in gpp is near-useless for high pingers like me.
Playercount - No body gives a fuck about gpp in 1.1, well at least the majority. Same for gpp against 1.1. I've already mentioned this many times in the past.
Also, more servers exist in 1.1. A good example is that there are still 3 servers that remain near me, Game Arena 1, 3 [4 doesn't exist anymore, 2 was removed] and Aussie Assault [Last updated: More so than gpp, has cool stuff like achievements] whereas in gpp the only one that's close to me is Wogomo's Asia Unofficial, which hasn't been updated for a while, although it is one of the "newest" builds in gpp. You could say tremulous 1.1 is more active in terms of modding and player count than gpp.
