Ok, the only thing I can really say about this one is, that it was a bit of a disaster.
I think the beach landing was ok for the first few minutes, and then it just got ridiculous. This continued throughout because I didn't name each AI spawn script a different name, so whenever we crossed ONE trigger for the script, ALL AI spawns fired, which lead to obvious chaos.
Next few missions don't involve that level of AI involvement, they are balanced and can be played at a more tactical pace.
Thanks to those that did attend.
