We're going to try a mission on the fly. We had a little go at it last week at the end of the evening with just four of us and it worked well. So we'll give a full mission a go.
If anyone has an idea for something we should be able to work it in somehow.
I have also written some scripts which allow me to change the AI difficulty on the fly, i'm hoping this will let us fine tune the AI so they are a little less dumb but not to the extent they're aim bots.
