It's worth it without
Not having played Payday before, I can see how it's totally addictive and why the huge following. Shock horror the teleporting hasn't put me off, because it's that manic.
After a couple of hours with it, it's another one of those where you think, why would I play this any other way. Having the ability to hold your weapon one handed around a corner laying waste to cops lined up to slaughter with room scale is immense.
The devs have done well for a first effort beta, runs like a dream, and it's all as decent looking as you could expect.
Having got the game for free, I feel the need to shower them with some cash in some way. Very impressed, very much the future for fps.
