Could you explain why you used Lead Engine name in this edit and also in Splinter Cell Conviction? https://www.pcgamingwiki.com/w/index.php?title=Tom_Clancy%27s_Splinter_Cell:_Blacklist&diff=954511&oldid=954510
Lead Engine is just internal name of current Ubisoft engine which is Dunia 2/AnvilNext for now, while these Splinter Cell games are clearly based on Unreal Engine 2.5/2.9. Check e.g. their configs for reference.
