There are 88 achievements now that Space Age is out. Let's see if we can round it out to an even 100. (Or 111)
These are just my ideas for some extra achievements and what they achieve in terms of player direction and challenge. Other users submitted their ideas too, so the subreddit post is worth a visit. I've copied it over here anyway.
1) I’m but a simple engineer
- Beat the game only ever crafting common items / without crafting quality items.
- (Crafting an uncommon or rarer item disables the achievement. The devs have said in FFF that quality is intended to be explicitly opt in, so let’s signal that.)
- Drop down to <planet> and launch a rocket without ever receiving supplies from orbit.
- (Achievement is disabled for the planet as soon as you send any supplies from a space platform down to the planet. The idea is to play the early game on each of the three inner planets, using stone smelters etc., the purest <planet> experience. Intended to be hint achievements that it’s possible to do this on these planets.)
- Have your only space platform destroyed by asteroids while on a planet other than Nauvis.
- (A rare example of a negative achievement similar to “Watch your step”. Might be too strict, but it's a consolation prize for your first ill-equipped ship's demise. Could just be, “Have any space platform destroyed by asteroids”, so it could also happen when trying to get to the Shattered Planet.)
- Burn 100k spoilage.
- (Similar to other production statistics achievements. Needs playtesting data to find an appropriate amount. Also I saw someone think you have to use recyclers to get rid of spoilage, not realising it's burnable.)
- Power a space platform with a nuclear reactor.
- (This is intended as a hint achievement to get to Aquilo, and a milestone achievement towards beating the game. The low rocket stack limit for nuclear fuel almost discourages you from trying, so this is to counter that a little.)
- Kill a large demolisher from full health in less than 1 second.
- (Might be too finicky so might have to play around with finding an appropriate time limit, but it would be fun to have some achievement involving late game weapons like railguns or luring worms into your trap set up. I'm not sure if a one shot kill is possible, but it could be with nukes or nuclear reactors. Or there's interesting scope for activating your defences with a power switch)
- Pilot a tank remotely to kill an enemy.
- (I did this in my playthrough, thought it was cool, and people might not know you can do this with tanks. Could also be a more general "Pilot a vehicle remotely.")
- Plant 10k trees.
- (There’s a whole tech for tree farming, and no real incentive to do it. So this is to encourage people to either improve their bases cosmetically with trees and clear up pollution, or make an infinite polluting wood burning power set up. There are two types of engineer.)
- Eat a fish, jelly, yumako mash, and bioflux.
- (Hint achievement to let you know you can eat all of these and they grant bonuses.)
- Build a biolab.
- (Technically it’s optional to return to Nauvis after Gleba with bioflux to improve your base with Biolabs, so it would be nice to note the player doing it. There’s already an achievement for Prod 3 modules, but nothing for Biolabs. It makes what I call "Nauvis 2" more of a milestone where you upgrade your old base with new buildings from the inner planets before you head to Aquilo. But uniquely, Biolabs are only built on Nauvis instead of the planet they're unlocked on.)
- Die to lightning.
- (This is actually pretty rare for lightning to hit you frequently enough that you die to it. The only reason this is here is for a Fulgora-specific achievement, since Vulcanus and Gleba already have achievements related to Demolishers and Pentapods. Could also be a much easier "Get struck by lightning.")
