I assume you mean stuff like different patrol routes, amount of guards, or camera positions, that really do work great with Payday 2, making the grind a lot more interesting. We have discussed this, but the feel was that it might not be as useful for The Masterplan as it is for Payday 2. One of the reasons for this is that in the final version you're not intended to repeatedly play through the same levels, but rather progress through them and move on. In the campaign setting, more variation will be provided e.g. by the gang management.

If we ultimately design against the variations in the maps, it means that we will address the need for replayability some other way instead. One major advantage for replayability we will have in the end is the level editor. With this, there will hopefully be plenty of truly unique content available with or without level variations. :)

Yes that is what i meant thanks for the quick response.

i must say i really hope you implement some kind of randomization, eg. for the placement of keys i have proposed some weeks ago.
its fine however if you want to focus on different aspects of the game until its more or less polished but it would add much if really bloody difficult levels were created that you want to play more often to get every last penny. perhaps this can be simply done with a possible leveling editor in the end where you select a few random spots for every item you place with a simple mouse-click. and the game randomizes this with a basic algorithm on every start of the level.
of course i have no insight, and if this really requires tremendous amount of work. i could live without it.

That does make sense. The priority is probably going to be to first make most of the campaign levels and then try to add the variations.
The random location key could work well just like you described. We'll see how it goes :)
