Gun Fanatic Achievement Glitch / Infinite Rocket Launcher Model not showing

[MekkieManul]

I've unlocked and purchased all 29 weapons, including the infinite rocket launcher, but my completion is stuck at 28/29. The Infinite Rocket launcher model isn't available for me to purchase in the extra content shop, despite the fact I've already bought it and used it in game.

I've tried selling and repurchasing, as well as moving it from storage to my case multiple times but nothing seems to work.

Has anyone else had a similar bug appear? Tried verifying game cache as well, but it seems like it's stuck with no way out.

try to eguip or put the Handcannon or the infinite rocket launcher in your attache case and then see what happens.

Screenshot of your models? I don't think there is an inf rocket launcher model since that's the same as a normal rocket launcher.

Also make sure you've at least grabbed the primal knife, tommy gun, and handcannon out of storage once. It doesn't count as acquired until it's been in your attache case (besides inf RL).

Did you unlock the handcannon via mercenaries? I believe I heard the gun fanatic wont actually unlock unless you finish the challenge that originally unlocks it. Not 100% on that though.

My mistake if that's the case. Here's a link to my models. I'm missing the one after the rocket launcher, which I assumed was the infinite rocket launcher but I could be wrong.

I've removed all 3 from storage, equipped them and fired them a few times just to be sure. Unfortunately it didn't seem to register.

I didn't, I got it by completing a S+ run. I haven't even touched mercenaries yet. That could be the case.

Update: It looks like the model I'm missing is a special rocket launcher that Ada gives you during the final boss. I cheesed the final boss using the normal rocket launcher and magnum so that may be the issue.

Pretty sure that one is the (Special) rocket that ada throws you at the very end.

Yeah, Saddler can be killed with just damage and you don't need to fire a rocket launcher special or rocket launcher normal against him. Kind of funny Minimalist runs don't count using the special rocket launcher as breaking the rules either (at least against Saddler).

In the original, you can save up like 3 or 4 special rocket launchers through repeated playthroughs. I think they just have like 50-100% more damage over the base rocket launcher?

Just reloaded my save file before the finale, it was indeed the special rocket launcher Ada gets you. The achievement popped off and my challenge shows as complete!
