</>What does Offline Fast-Forward do?
Offline Fast-Forward hands you the 'welcome back' payout on demand instead of making you actually close the game for hours. Set how many hours you want to simulate, press the button, and the real catch-up rewards screen pops up and drops everything you would have earned while away — exactly the way the game already does it, no fake numbers. Great for topping up before a big push, testing how a new setup performs over time, or just skipping the slow overnight wait. Heads up: the game caps how far a single offline collection can reach (about a day, or longer once you've unlocked the upgrade that extends it), so very large hour values get trimmed to that limit.

What does Offline Fast-Forward do in Unnamed Space Idle?
Offline Fast-Forward gives you Unnamed Space Idle's 'welcome back' catch-up payout on demand, without making you actually close the game and wait. You choose how many hours of being away you want to simulate, press the button, and the game's real catch-up rewards screen pops up and hands you everything you would have earned in that time. These are genuine rewards, not invented numbers — it's the exact same payout the game gives when you return after a real absence. It's perfect for topping up before a big push or skipping the slow overnight wait. Offline Fast-Forward installs in one click through ProjectMods.
How does Offline Fast-Forward decide what I earn?
Offline Fast-Forward doesn't make up a number — it runs the exact same catch-up calculation Unnamed Space Idle uses when you come back from a real break. When you set your hours and press the button, the game figures out what your current setup would have produced over that stretch of time and shows it on the normal rewards screen. That means your payout scales with how strong your production actually is: a well-built ship earns far more per simulated hour than a fresh save. Because it leans on the game's own math, the results are always consistent with what you'd get by genuinely leaving the game closed for the same length of time — just without the waiting.
Why do very large hour values get trimmed?
Unnamed Space Idle caps how far a single offline collection can reach, and Offline Fast-Forward respects that cap. Out of the box the game only banks roughly a day's worth of progress per collection, so if you ask the mod to simulate a week, it trims your request down to whatever that ceiling currently allows. This isn't the mod under-delivering — it's the same limit you'd hit by actually leaving the game closed for a week. The good news is the cap grows: once you unlock the in-game upgrade that extends offline time, your maximum stretches out and larger hour values start paying in full. So if big numbers feel short, chase that upgrade and Offline Fast-Forward will reach further.
How many hours can I set in Offline Fast-Forward?
You type in however many hours of offline time you want Offline Fast-Forward to simulate in Unnamed Space Idle — there's no artificial low limit, so small top-ups and big overnight-style hauls are both fair game. Fancy a quick two-hour boost before a session? Enter two. Want to see what a full day away looks like? Enter twenty-four. The one thing to keep in mind is the game's own offline cap: whatever you type, the actual payout can't exceed what a single collection is allowed to bank, so very large values quietly get trimmed to that ceiling. Set your number, press the button, and the rewards screen shows exactly what you're collecting for the hours that counted.
When should I use Offline Fast-Forward instead of just waiting?
Reach for Offline Fast-Forward in Unnamed Space Idle whenever you'd rather not leave the game sitting closed for hours. The obvious case is skipping the overnight wait — grab your morning haul the moment you sit down instead of remembering to quit the night before. It's also great for topping up right before a big prestige push, or for testing how a new production setup performs over a simulated day so you can compare builds quickly. Because it uses the game's real catch-up math, it doubles as a fair way to sanity-check your progress rate. When you want the payout without the downtime, one press through this ProjectMods mod hands it straight over.
