It's Postal alright. I can't say much about it, just play it.

The weapons are crazy unbalanced, levels are what you would expect from a arena boomer shooter. DUKE NUKEM KICK BABY. The artstyle reminds me of Dusk. Doom Eternal shotgun chain, awesome.

Now, the levels might get or look boring an uninteresting as time goes on. Weird because it's start very good with the Suburbs. The rest is oddly generic.

It's a good time outside of that.
