ae_sniper_night 0.01 now posted with lever support.
It provides examples of how to add fixed mg42s and teleports by scripting. It also provides an example for how objectiveless sniper maps can be made to have dynamic changes to vary the play. Here the bots are shifted from snipe only defensive positions to attack and snipe positions based upon the state of the power on the "telephone" wire and some randomness.
There are enough camps and roams to make this a playable map but there are more positions for you as a would be waypointer to fill and learn. Also try changing the bot_SightDist in the aiscript to vary the difficulty.
And included inside is a text file describing a few suggested exercises for would be waypointers.
