Eight trophies that only exist between sectors: what to do every time you return to the Shelter
Talking to Diana opens four trophies in a chain, Cabin's boards unlock what Can't Stop, Won't Stop asks for, and the 30 sims require six collectibles many never connect to them.
And it counts towards Thanks for Everything!, Peekaboo, For Me?, Replicating Extraordinaire!, Blackout!, Mister Simulator, Master of the Simulator, required for the platinum.
Diana: five trophies for talking again
The Shelter is the base between sectors, and Diana is always there. The chain starts with Small Talk (94.1%): approach her and keep talking until it pops. From there, every conversation opens something new.
For Me? (89.4%): gift her an REM, the holographic toys collected across the sectors. The first is picked up automatically. Replicating Extraordinaire! (66.9%): there are 16 REMs and they form series; one complete series gifted awards the trophy, and all 16 are needed for sector 100% anyway.
Thanks for Everything! (84.2%): by talking and gifting, Diana gives you a picture back; you receive four across the run. Peekaboo (65.7%): at some point she proposes hide-and-seek; accept and find her, the Shelter is small.
The numbers tell the story: 94.1% talk to her once and only 65.7% get to hide-and-seek. Almost a third stop coming back to talk. The rule is simple: every time the tram drops you in the Shelter, talk to Diana before heading out again.
Cabin and the 30 sims
Cabin is the Shelter's robot with four Stamp Boards filled with coins: 9, 16, 16 and 16. Coins come from Safe Boxes, from Diana as a reward for REMs, and from the sims. The first board awards Blackout! (69.8%), but completing all four is worth it: several weapons and abilities that Can't Stop, Won't Stop asks for only unlock that way.
The Training Sims are 30 missions, opened in two ways: by upgrading the Shelter after each boss and by collecting the 6 Training Data spread across the sectors. Without those six collectibles the list cannot be completed, and that detail is why Master of the Simulator sits at 13.4% against 72.2% for Mister Simulator, which asks for just one.
Each mission has one main objective and two side ones: only the main objective counts. And several sims are the best spot for other trophies: 07, Project Pierce, for the 6000 damage of IT'S OVER 6000!; 10, Mouse Trap, for burning twelve enemies with the recycler in Round 'Em Up.
The 30 sims do not open with the bosses alone: six depend on the Training Data hidden across the sectors. Without them, Master of the Simulator is impossible.
