- The general rule is that if you can't find a code for a safe or puzzle in the immediate vicinity, leave and come back when the quest indicators tell you to. This especially applies to the puzzles to get people in the same room together, you'll be pulling hints from all over the timeline, and there are some puzzles that *look* like the solution is diagramed out for you in the room but it's just a red herring.
- You don't need a copy of a Slab equipped in order to get upgrades for it to drop, and you don't need to have infused it either; you just need to have picked it up once. This means that even if a given Slab doesn't appeal to you, at least pick it up (and then pick your old one back up) so that on subsequent kills you can still get the upgrades, which you can infuse or sacrifice as you wish.
- Don't bother infusing the double jump. You can consume it at the end of each round for an extra chunk of change and it will come back automatically at the start of each round.
- There's not much point exploring in the first loop, it's heavily scripted and you won't be able to keep anything from it except maybe the held weapon (not sure).
- Experiment with loadouts a lot - some non-immediately obvious upgrades and trinkets can be very powerful or very fun.
- There are only three silenced weapons in the game - you'll find one early enough and the other two are the pistol and SMG with a (randomized) modifier.
- You don't need to worry about missing something in loop format too much, the game keeps track of everything important and holds your hand quite a lot.
- While there are multiple endings, there is only one path to get to the decision-making point.
- The free Goldenloop update in September 2022 added a new weapon & new ability; both are hilariously overpowered at their primary function (the gun absolutely melts Visionaries, and the ability allows easy kills of massive groups of minions)
