Last night's surprise Helldivers 2 update also added its first FOMO weapon: The stun baton is only in the rotating Superstore right now

pcgamer.com:

My feelings on the Helldivers 2: Omens of Tyranny update so far can be described in bursts of «oh this car is awesome» and «are you kidding me the Illuminate are incredible,» but there was one surprise waiting for me in Helldivers 2 this morning that I wasn't happy to see: Arrowhead isn't just selling armor in its store tab anymore, but weapons too.

Well, one weapon for now. The stun baton, one of two melee options new to the shooter, can only be unlocked by purchasing it directly from the Superstore for 200 Super Credits. Unless I've been living under a rock, this is the first time Arrowhead has sold a non-armor item outside of a warbond—Helldivers 2's battle pass-like progression system. I'm uneasy about the precedent that sets for the future of the game.

In these first 10 months, the relationship between the Superstore, warbonds, and normal level-based progression in Helldivers 2 has been clear and consistent: You can unlock strategems and most weapons just by leveling up, warbonds offer optional expansions to your arsenal, and the Superstore is an even less crucial cosmetic shop with more armor sets. I really liked that setup—I even called it one of the best monetization schemes in ages—because Arrowhead's warbonds are generally a good value, they don't expire, and even the premium armor sets have the same perks as warbond armors and are only a few dollars.

But Arrowhead has slowly expanded its boundaries around what and how it charges for non-cosmetics. The stun baton being a Superstore exclusive is the latest example, but I first noticed a shift in the Chemical Agents warbond in September, which included the first premium-only stratagem in the «Dog Breath» drone backpack. I felt my foot slipping on a possible slope at the time, and it's happening again in Omens of Tyranny.

The stun baton isn't worth raising any alarms over on its own. It only costs 200 Super Credits ($2 worth of credits) and Helldivers 2 still doles out a decent amount of free Super Credits by
