Ok, I'm gunna be completely honest with you. The needler turret sucks.
So I finally modded a map with turrets on it, and replaced it with needles. I realised after the release of Sindewinder that the needler turret sucks and it needs a better, more powerful projectile. Perhaps a plasma pistol bullet charged? Since turrets are under-used anyways, so swapping the projectile with something more deadly could make the stationary weapon become lethal for online and campaign play.
Have a better idea for a projectile? Leave a comment and tell me what you think. But just on a quick note: No ridiculous suggestions and bare in mind that the turret shoots 3 of one projectile at a time so no requests like "rocket launcher" or "scorpion rocket" since that will just ruin game play. Leave a comment, all comments will be read and taken into mind!
