I made a small update to this, but it is getting closer to a system that I can just add mission content to.
The player is limited to five homing missiles per mission.
The missions have a log/dialog system, so that messages come up as the situation changes.
I rearranged the third mission to avoid the slowdown I was experiencing. It still happens, but is a little less.
As ever, little AI tweaks. The enemies have their quirks, but I enjoy seeing them chase the player around!
