10 Deceptive Video Game Achievements That Sound Easy To Get (But Actually Aren't)
3. Outside Context - Stellaris
Stellaris, Paradox Interactive's sci-fi grand strategy, incorporates a mechanic that allows you to invade primitive planets that haven't achieved proper space-traveling technology.
Pre-FTL invasions are as simple as sending a single army unit over the desired planet, but this said, if you want to get the "Outside Context" achievement, it'll take far more than that.
On the surface, all the achievement requires you to do is invade a pre-FTL planet while its residents are at war. However, because of that one simple clause about war, this achievement turns from one of the most basic actions in the game into the hardest gamble of your life.
The thing about wars is that unlike other information about the primitive civilizations you visit, they aren't mentioned anywhere.
You have no way of knowing if the civilizations you invade are currently at war with each other, and since the event is randomly generated, you'll have to blindly attack every primitive planet you see, hoping at least one of them has the correct prerequisites for the achievement.
Don't worry, though! It's not mass genocide if it's for achievements!
