While you are in the Shop, you can purchase permanent Multipliers for your profits. Once you purchase a multiplier, it will multiply the base profits of all of your investments on that specific planet. Multipliers will remain, regardless of how many times you reset to claim your Angel Investors. Multipliers affect both online and offline progress.
Please note that multipliers are planet specific, and only affect the investments within the planet they are purchased within.
After you purchase your first multiplier, you will unlock larger multiplier options at a discounted price. One thing to note with your purchased multipliers; when you purchase more than one, the totals add together, and do not compound.
3 purchases of x3 multipliers: x3+x3+x3=x9 Multiplier on base profits
On Mobile, purchased multipliers are device specific and do not sync/transfer within your devices (just like your progress)
On Steam purchased multipliers will transfer across locations, as long as your are playing online and saving your progress through the Steam Cloud.
