Hi
No, this is the original EECH being modded. I did not bother with Enemy Engaged 2, but it looks like most people that have tried both prefer the modded original. EECH with 1.9 exe is really great and Arneh one of the leading modders seem to come up with more and more good stuff.
In the meanwhile EE2 people are hoping for a patch... same old story...
I can really recommend 1.9 exe with the superpatch which give you all the mods, campaigns etc in one go. At least it will make the wait for Black Shark a bit easier.
