If they can't be placed as the 94th and 98th tier reward, then at least place them as mission artifacts or NPC drops.

Aidonium compactor (or shrinker) -> Reduces Aidonium space size by 1. Limit: 4 compactors/shrinkers.

Invasion force teleportation bay: Reduces invasion costs by 10%. Limit: 5 teleporting bays.

Point of this being? If you say to save you cargo space...get more artifact production. I have have 15k free space and growing and I haven't been able to use the ctl in over 3 weeks I can make about 20 recipes making my free space go for 15k to 18k rather quickly. I can fit 1k Aid in my cargo and still have room to collect an entire mineral shipment. I am not a high rank, I am maybe considered mid rank on the lower end. No one above the rank 300, who is playing in a smart manner will need this.



That reduces invasion down to about 55% which is barely above colonization. Maybe a limit of 1 or 2.
