its also good/bad that its super easy for a tiny organized squad to completely dominate the game. for the beta at least, the game mode is armored heist. defend your "vault", grab money from the central fallen truck, steal money from the enemy vault. The game ends when all (?) the money is in one teams vault.
With respawning on team-mates and a relatively short distance between money and vaults, it was a bit ridiculous how fast you could move money (500k/person, 5m max money) around, especially since you can use vehicles while carrying money.
i hope they have a lot of game modes though, payday 2 is hella fun in a small team since there is a big variety of PVE missions.
