Defender Turret

Auto aiming turret, simple and reliable.
Located in "Other" Entity tab.

Usage
Spawn it and press E to enable/disable the turret then place it on whereever you want, easy.
Its not recommended to place too much of it, which may cause performance problems.
If you are unsatisfied with the default settings( bullets/ laser/ scanning/ etc ), you can edit it in the context menu( Hold "C" ).

Filter
You can set the whitelist for your friends/NPCs, and turrets will not target them.
Edit filter in the context menu, the section is below the "Edit properties" one.
I havent tested the player filter for Im always playing in singleplayer, and Id appreciate it if someone can test it out for me.
And also, if you want more detailed "NPC Classes" filter, ask me as well.

Protection
The turret is admin only, for its too OP to be on servers.
Only the owner can edit/move/tool the turret, and if the owner is disconnected, other admins can get rid of it.
Once disconnected and rejoined, drag the turret or press E on it to reclaim it.
