Looks like we may soon be getting more things to buy using samples and requisition slips. The Catalog Expansion has no cost, and buying it does nothing. The Upgrade Effect text must be null for Catalog Expansion, that field just shows the effect for whichever upgrade was previously selected.
Edit: It's been acknowledged on the official Discord, looks like it's unintended:
ALERT: ROGUE ITEM DETECTED. The Ministry of Truth has confirmation that a rogue item called the "catalog expansion" is temporarily visible in the Ship Management menu and, in accordance with regulations, we instruct all Helldivers to avoid this rogue item until further notice. The Ministry of Truth cannot confirm the reliability or safety of this item, nor can they confirm its origin.
Literally what I'm gunnin' for, honestly. I'm gonna go full Ripley on the broodmother. (Well, that and the Quasar and a couple other fun toys along the way!)
I guarantee at least a third of the player base would pitch a fit if they put some stratagems behind a high level requirement. As it stands, the level requirements are largely meaningless after your first 30-ish hours of playtime and I don't think that's a problem.
I'm almost to 30hrs, I think? More than 20, that's for sure. I get the "hours logged" mixed up with the others at the top of my Steam dashboard (Elite Dangerous, Skyrim, etc.) If I'm being honest, I could have twice that, but I can't check rn.
