Nope
All the basic schemes in these new worms titles are the same as in WA really. Beginner to Pro, then BnG, some kind of shopper and in Reloaded rope race. And that's it.
The only thing WA misses are the automatic timecount in TTRR when you touch the finish point & the forts mode in Reloaded. The last is basically same as WA forts, but with easier forts, that are nicely designed. It's a pretty fun game mode. (edit: I made a WA version of it, here:
https://www.tus-wa.com/forums/schemes/fun-forts-wr-style-forts-but-then-for-wa-9233/msg72864/#msg72864 , but yeah, the W:R forts are prettier)
The W:Rel. maps there are worth copying, but unlike in WA/WWP they aren't in an accessible format like png or bmp. Neither is it easy to copy them through screenshots, cause you can't remove the colourful background with insert key or something like that.
User created maps are likewise hidden behind inaccessable formats. And they are in a different size as well (much bigger I think).
It's sad. A lot of these new things would be nice to implement in WA. Like that Clan Wars thing. That would be kinda sweet to have on wormnet... but yeah.. don't think they will ever allow our WA code team to do that.
The only goodies that you can use in WA are the soundbanks from Worms 3D (not sure about Mayhem). With some editing they can be a nice addition to your WA, but yeah, can't share them over the net cause copyrights. Other than that, all these new titles are worthless for us.
edit: regarding schemes: the WA/WWP versions on PS had some different schemes that can be altered to fit into WA. Aerial scheme comes from the PS version too
Totally edited though, but the idea is from there.
You can find them on Jon Skeet's page:
http://www.yoda.arachsys.com/worms/wa/psxschemes.cgi But not all options are visible there, so you can't just 'enter' them in Worms. But it can be nice to get an idea?
