You want it star wars correct right? Then the turrets will have to be really unaccurate, as all rebels got shot down by the ties in the movie. The turrets were designed to guard the deathstar from a large scale attack with Blockade runners and frigates and stuff like that. The rebels knew that and sent the small fighters that had no problems with those huge slow turrets.
Porkins died because he was overconfident
A random script would be nice because I would rather be shot down by a fighter than a turret. Just make a lot of lasers that make it seem more intense.
turrets make the map more real and I think u can have 100 players on one map (but with alot of lag I guess), so it would be possible with patch 1.3 to have 20 blasters (bots) and still 30 players I think
