Lego Marvel How to Get Deadpool is one of those things that seems complicated until someone states the one rule it hangs on.
The advice that sounds too simple is usually the part that actually matters. Anything presented as a hidden trick is normally just a step that a popular guide left out. The version number is the single most useful thing to note before following instructions.
The quick answer
Get the basic version working, confirm it, and only then optimise — reversing that order is where most of the time goes.
Doing it faster once you know the method
The steps are boring on purpose; the interesting version is the one that fails half the time. Where several approaches exist, the popular one is popular for being easy to explain rather than best. Most guides are written once and never revisited, which is worth remembering when one does not match. Where two methods both work, prefer the one with fewer places to go wrong.
Getting a better result
It is worth knowing which part of this the game actually enforces and which part is convention. Consistency beats optimisation until you are comfortable, and often after that too. Doing this without understanding it works fine until something changes, which it will.
If the result looks wrong immediately, stop rather than continuing and hoping. Understanding the reason behind a step lets you adapt it when your situation differs. The second time takes a fraction as long, which makes the first attempt worth doing carefully.
How to check it worked
A result that works but that you cannot explain will not survive the next change. Small details matter more than they should here, so read the order of steps carefully. The step people skip is almost always the one that makes the rest reliable.
Terminology differs between communities more than the underlying behaviour does. Written notes beat memory when you come back to this in a month. Half the confusion online comes from people answering a slightly different question than the one asked.
Edge cases worth knowing
The simplest explanation that accounts for what you are seeing is usually the correct one. If the explanation feels overcomplicated, it probably is — the working version is usually short. A change that works but that you cannot repeat has not really solved anything. Start with the simplest option before touching anything that is hard to reverse.
- Prefer reversible changes over permanent ones.
- Do the simple version first, even if you intend to refine it.
- Set aside enough time to finish, since stopping halfway causes most of the confusion.
- Save the original settings somewhere retrievable.
- Check whether an update landed since you last played.
Traps to watch for
- Making a permanent change to answer a question a reversible one would have settled.
- Skipping the preparation step because it looks boring, then repeating the hard part four times.
- Optimising the easy part while ignoring the step that actually costs time.
- Following the detailed method when the simple one would have done.
- Assuming a step took effect without checking.
Loose ends
Is there a faster method?
Usually yes, and usually it is riskier. The route above trades a little speed for a much lower chance of having to start over.
Does this still work after the latest update?
It did at the time of writing. If a step no longer matches, the underlying idea normally still applies even when a menu has moved.
Why do two sources say different things?
Almost always because they are describing different versions, or because one of them repeated an assumption without testing it.
Come back to this if you hit the same wall on a different save; the shape of the problem rarely changes.
