You can knock down redwood tree saplings then in the spot where it used to stand place these and then build an inconspicuous 1x1 hut with a generator inside so that after enough time has passed the redwood sapling will have regenerated completely concealing the auto turret and can fire at creatures even when its whole model is inside the tree.

Gigas can't damage these so if you are on old mobile then fill every slot with bullets then it will die, if you are on other platforms fill half the slots and it should be enough to kill it. The giga will also last around 6 minutes before it dies using one auto turret, so get some popcorn or start recording for that clip.

Note that if you are on old mobile it takes 80 metal and 720 gunpowder to craft 1200 advanced rifle bullets, but on other platforms it will take 600 metal and 5400 gunpowder.

Don't use near your breading pen because it can kill new born babies(not claimed onces).

Can be set to target different things and if what it targets gets in range it shoots at it, using advanced rifle bullets, this requires power and can be turned on or off

Very usefull, great for late game xp
