Bring back space spiders damaging small grids
I had SE around when it first came out and I got really into it when planets was released. NPCs was released with them too. Not the brightest npcs but you can have some fun with spiders. At the time they had amazing path finding were they can actually follow you through a building. They can even damage grids though I wasn't into repairing my base walls because of it.
However having a small grid dropship landing on Alien and having spiders actually climb aboard and actually start breaking the ship was awesome! Than I found a modded planet were it was like 30 spiders coming out and I had SOOOO much fun with friends because how dangerous spiders are and pretty much a swarm going to make you think twice before landing. Than sadly spiders lost the ability to pathfind decently along with damaging grids. They come at you and dig, you can completely be safe if you sit in a seat...
I just want some Starship Troopers level of fun again. I would love it to see space spiders actually be a threat to engineers and small ships. Just have them leave static and large grids alone or mainly static grids . If people don't like Spiders attacking small grids put it in a hangar or tick them off in the settings its simple. Just don't dumb them down to the point they are harmless. We're talking about a GIANT SPACE SPIDER not a cute puppy.
Another quick idea- Bring back exploding Cyberhounds that run with the wolves but rarely appear? seems like a waste of a good idea or at least put them in the game as a option. I modded a planet and wouldn't mind more NPCs to pick from.
