The first one, the standard version, contains the basic game itself and contains no other content;

The second one, Deluxe Edition, is Digital Deluxe Edition. In addition to the game itself, there are official soundtracks (music files such as the soundtrack in the game) and official digital photo collections (including people's designs, original maps and design drafts). ), and there are two masks for payday 2 (another game, Harvest Day 2). In fact, there is no difference in the game itself, except that some things around the game and props linked to Harvest Day 2 are added, which belong to the choice of fans and ordinary players do not need to buy;

The third and fourth are the same bundle, including the game itself and the sawed chapter expansion package, in which the game itself remains unchanged.

Buying other versions has no effect on the game.
