Mafia 2 Definitive Edition offers all of the base game’s DLCs for free. However, PC gamers need to create a new 2K account in order to acquire them. In case you don’t want to create one, you can unlock of the game’s DLC by using the following mod.
This DLC unlocker unlocks all suits and all cars from the Mafia 2 DLCs. Furthermore, Mafia 1 DLC, Mafia 3 DLC and Made Man Pack DLC are unlocked immediately. This mod works with the Steam version, and will not force you to create or use a 2K account.
On the other hand, modder ‘alteredbeast’ released a new mod that enables an car interior viewpoint. This mod comes in two versions. The first one replaces the third-person camera with a free view camera, and adds an interior view. The other mod has the default third-person and the new interior camera.
Now as we’ve already said, we suggest playing the vanilla version of Mafia 2. After all, the Definitive Edition has some performance issues on older hardware. It also lacks some of the GPU-based PhysX effects.
It’s worth noting that 2K Games claimed that it will address most of the game’s issues via post-launch patches. Still, I wouldn’t expect any major improvements on the PC version. 2K Games will most likely focus on the console versions as those version perform even worse than the PC version.
