Reactor

The Reactor screen

Reactor is one of the systems in Unnamed Space Idle, unlocked upon reaching sector 5. Here, players can convert Void Matter into power, which can then boost various systems.

Void Power Generation

Void Power Generation Stats

Stat name	Icon	Description	Base value	Base upgrade cost	Effect per level	Cost scaling
Void Matter Conversion Max		Maximum amount of Void Matter that can be loaded into the reactor at once.	0.5	1000	+0.5	x1.3
Void Power Generation		How much power each Void Matter can generate every second.	15	100	+1	x2
Void Matter Conversion Time	(no image)	Duration Void Matter lasts while being converted to power.	8	200	+0.5	x2
Max Concurrent Boosts		Number of power boosts that can run at once without incurring a penalty. Running more power boosts than this stat will multiply the drain of all power boosts by Number of boosts active - Max Concurrent Boosts + 1	1	N/A	N/A	N/A
Max Void Power		Maximum Void Power capacity.	1000	N/A	N/A	N/A

Power Boosts

Power Boosts increase the efficiency of several systems by draining void power. These boosts wil last until you turn them off or you run out of void power to sustain them.

Depending on your Max Concurrent Boosts stat, having multiple boosts active can multiply the drain on all power boosts.

Power Boost Stats

Name	Effect	Drain/sec
Boost Engine	x1.25	3
Boost Compute Speed	x1.5	5
Boost Salvage	x1.5	5
Boost Synth Speed	x1.25	10
Boost Damage	x1.25	15
Boost Max Shields	x1.25	15
Boost Research	x1.25	25

Reactor Boost Levels

After getting the "Reactor Boost Levels" upgrade from Base 1, Void Power can be spent to increase the maximum level of power boosts where higher boost levels are stronger but also drain more Void Power. The level to run can be adjusted for each power boost.

Void Power drain doubles every level. Cost to increase max level multiplies by 1.4 per level, except for Boost Engine, which multiplies by 10000 per level instead. Boost Engine caps at level 30.

Void power cost to upgrade and drain scaling per level can be reduced with Power Hungry challenge completions.

Power Boost Levels

Name	Effect per level	Base void power cost
Boost Engine	+0.25x	2.00e5
Boost Compute Speed	+0.5x	4.00e5
Boost Salvage	+0.5x	4.00e5
Boost Synth Speed	+0.25x	8.00e5
Boost Damage	+0.25x	1.60e6
Boost Max Shields	+0.25x	1.60e6
Boost Research	+0.25x	3.20e6

Uncapped Power Boosts

Getting the "Uncapped Power Boosts" upgrade from Base 4 will fix max level of all power boosts(except boost engine) to level 999 and cannot be improved further. This removes the need to buy max level increases for power boosts.

This upgrade also unlocks milestones for bonus scalings. Milestones are self multiplicative and getting a new milestone will replace part of the old one. For example, if you have 1e60 Max Void Power, level 500 to 600 have x1.01 per level and levels above 600 have x1.02.

• 1e50 Max Void Power: x1.01 per level above 500
• 1e60 Max Void Power: x1.02 per level above 600
• 1e70 Max Void Power: x1.03 per level above 700
• 1e80 Max Void Power: x1.04 per level above 800
• 1e90 Max Void Power: x1.05 per level above 900

Power boost effects at 1e90+ Max Void Power and level 999:

• Engine Speed x8.5(unaffected by uncapped power boosts)
• Compute Speed x1.45e9
• Salvage Amount Multiplier x1.45e9
• Synth Speed x7.25e8
• Damage x7.25e8
• Max Shields x7.25e8
• Bonus to Research x7.25e8

Overdrives

Major Spoilers for R1, Sectors 83+ (click here to dismiss)

After Reinforcing once then reaching sector 83, reactor can be upgraded to massive reactor.

Upgrading to massive reactor multiplies Max Void Power by 1.00e7x and automatically sustains all 7 power boosts at max level(lv999 on 6 boosts, 1e90 Max Void Power, boost engine will be raised to lv36, giving a x10 effect rather than x8.5) without draining any Void Power.

Reactor can now charge up various overdrives, giving 3 effects:

• An active charge, which can be stored for up to 5 charges each overdrive, and when used give a large temporary boost. Using multiple charges increases the duration but not the effect.
• A small passive effect that is self-additive.
• Every 100 passives causes the overdrive to tier up, giving a tier bonus, where any new passive effect obtained is 10x as powerful, but that overdrive also takes 10x longer to charge.

At base charge speed and tier 0, each overdrive takes 12 minutes to charge. Overdrive charge speed is unaffected by Void Power Generation, instead Void Power can be spent to upgrade overdrives' charging speed, with each having a base cost of 1.00e111 Void Power and cost multiplying by 1.3 every level. Each level multiplies charge speed by 1.02.

Overdrive Stats
