Not worth the money or at least the full price. There is no button to exit the game or for settings and the buttons too. And for some stupid reason there is cloud save and not settings. There are bugs. Nothing serious, but still. Enemies sometimes reappear for no reason and sometimes several times. There are lots of weapons and leveling up but no enemies. The story is unoriginal and boring with two endings not special and dumb. The scenes are few and there is not much variety. No point in replaying. The game has so few things that it looks like half a game and is downright pathetic, and everything similar to it, and given that it's 2025, it's even more pathetic.
