I've reorganized the mission, changed the lore a bit so it has a meaning and doesn't feel that empty.
Any feedback is welcome as always.

Yes, i agree on that point, I admit this one was a bit rushed due to lack of time and also loss of interest of my friends on playing zombie games. I will eventually find an extra time and fix the lore in this mission which is kinda weak (yes I know) and also make it the final part.
I already have some ideas to make it more fun, but it will take some time.
Cheers for your comment, really appreciate any constructive and honest comments like your's to improve my mission making.
Cheers mate

Just did this as well. Obviously, not quite as involved as the other two, but the few minutes on the other island were fun anyway. Thanks
