If I remember, there's one you get in a mission that you don't find by purifying a tower. This does count towards the achievement though. I want to say it's in the last Shelob memory mission, but I could be wrong.

As ScutumMagister said, you do have to at least load several of those games for achievements towards the Rare Replay 4000, but you don't have to really play them. Once you've loaded them and gotten the achievement, you may be able to delete them off your profile on 360 if you have 0 Gamerscore for that title.

You only need 45 seconds to clear the Snapshot, but for the achievement, you have to complete an entire loop of the level.

Some of the Chrono Castle rooms are challenging, but I agree with the others here that the platforming was pretty spot on. With some practice, you'll be able to get them done.

They said on reddit that they will be patching what they believe to be the issue soon, so taking a break before going back to it might not be a bad idea.

I've been playing offline and haven't had a completely corrupted save, but I did have one issue that made me have to restart. I was starting the Mad Hatter case and was fighting the goons at the beginning. It appeared to be a good room for the particular Shadow Vigilante challenge I was on, so I restarted after missing what I was going after. When the game reloaded from the restart option, I was falling continuously. Restarted again and the same thing happened, so I quit to the main menu. When I chose my safe file, it showed the file I was on and everything looked fine. Showed my percentage and difficulty correctly. However, when I clicked Story Mode, the Continue Story option was no longer available and it was replaced by the New Game button. It seemed to know I had a game in progress because when I pressed New Game, it asked me if I was sure I wanted to overwrite my current game, but I had no option anywhere to load that particular game back up. Even weirder, when I started the game over, I had all my Riddler packs still collected, all my upgrades, etc. I even had the story related gadgets straight from the get go, well before they'd normally be obtained. The only things that had gone away were my progress in the main story and the cases that I had done and the progress in the Dark Knight challenges. Still annoyed to have to restart, but at least I don't have to re-collect the Enigma packs that I had found so far.

Fixed and added the tip. Thank you.

Anyone know how I can edit the title of the thread and get the "WIP" out of the title?

I'm waiting for the staff to update the tiles for the secret achievements so I can add them to the guide, then I'll submit it. They've already been uploaded by WORLDEATER, just waiting for the update.

You can play them offline and it'll count towards your achievement just fine. You just won't be able to upload your scores to the Xbox LIVE leaderboards.

I can confirm this also. I did this once during my run through of this level on easy for this achievement and it still popped for me.

Yea, I took Arclight out first as well. Although I had ammo, so I just lit her up with the SMG from a distance. Blockbuster is pretty easy to dodge, even with Vertigo around, so I took care of him second. As for the Sinsters, I just used the Hammers so that they slowed down and I could make sure to dodge easier and used my Momentum moves whenever there was a buffing enemy or whenever I got surrounded. The SMG Momentum move is great for recovering health if you've got a lot of enemies around and get low on health.

Guns really are your best friends on Ultra-Violence mode. The counter from the pulse rifle also replaced most of my melee. It'll kill many melee enemies in 1 shot, plus since it's a counter it doesn't use ammo. For the ranged guys, the SMG drops them pretty quickly. The shotguns at close range will kill the big enemies fast also. Once these guns are upgraded, they make Ultra-Violence a lot easier. Also, if it's your second playthrough and you just need the achievement for beating it, you can teleport through a lot of the level. You'll hit checkpoints along the way, so if you get caught and swarmed by enemies, you'll just restart at the nearest checkpoint and many of the enemies will no longer be there. For the parts you can't teleport through though, guns do the trick.

It is on my card.
