LwAmi developing was ended 10 years ago. This mod was quite good at the time but now is obsolete and very unstable.
I don't recommend it at all. FPSchazly and Smartwargames just don't likes Reinforce Alert so they both suggests LwAmi is better - but its not truth.
Just watch FPSchazlys LwAmi videos and count how often his game crash.
Uploaded (for some time LwAmi) 3.11 full on my google drive.
