Research Inventory Size V

Research Inventory Size V is a research project with a relatively heavy research requirement: it costs 300 of each of five research inputs, plus 120 seconds per item to complete. As the fifth entry in the inventory size line, it belongs to the late progression of the research tree and is meant to be taken after the earlier inventory size upgrades.

Because it is a research upgrade rather than a placeable object, its main value is in advancing your available technology rather than producing anything directly. Players planning around it should account for the high multi-resource cost and the time investment, since it demands a broader research base than earlier upgrades in the same branch.
