The developers removed some content among art and animations that deemed questionable. This includes some nazi-like insignas, panty shots, a sovet announcer and the redesign of an oversexualized female combatant.

While for many this could look harmless or necessary, the issue is that the players paid for said content when the game was released (and funded). Even more, the devs made the oversexualized characters their main selling point for the game and everyone that decided to chip in and buy did it because they liked that aspect.

Now, ten years after its release, the developing team decided to remove and cover some of the promised, advertised and sold content, and the players are complaining because it's simply not the game they paid for. Not anymore.
