[rant]One thing for space vines. CLOSE THE DAMNED FIRELOCKS. FOR FUCKS SAKE. Nothing is worse than clearing a room, moving on to the next one, and finding that someone passed through, and didn't close the damned firelock, letting the vines in again! And the chef didn't help, opening the locks in the kitchen, after I had cleared it, allowing the vines to get back in. I quit trying then, because fuck space vines, and fuck their tiny little hitboxes.[/rant]
Dude, get the QM to order a Weed Control crate. It has Weedkiller grenades and a Scythe. The scythe will kill FOUR squares of weeds, INSTANTLY per click. Vines are seriously not a big issue if you order Weed Control Crates. Scythes are fucking bosslike. And also, they make the Chaplain look awesome.
While Scythes work quite well on space vines, they are wildly inferior to the real fix for space vines. The real fix is called Pete.
He's a pretty cool goat, and he doesn't afraid of space vines.
Also, the OP nature of borgs (especially Sec Borgs) is basically the most popular topic of conversation on SS13 boards. Because they are way, way better than their human counterparts. I also agree that hacked sec borgs are just way too good.
To stun them, you have to get right up on them, and use a flash. They'll be shooting tasers/lasers at you, and backing out of range while you attempt this.
When you finally stun them, hopefully you've got a very damaging weapon on you, you'll need to kill them before you run out of flashes.
