@Tfmonkey I don't know what your PC is like, but if you truly enjoy modern post-apocalypse then I am happy to introduce you to: STALKER Anomaly.

It is the three games combined into one giant map and experience. It is the ultimate STALKER experience for FREE!
@ButtWorldsMan @Tfmonkey I second this. Very nice open world shooter with lots of customization of the difficulty.
