How come nobody mentioned Dying Light? I used to play this for hours. The ability to travel a huge map with a off-road buggy or just your feet and parkour abilities and completely annihilate every zombie in your path with any weapon of choice and I mean you have a huge selection, from melee to explosives but not just that, you can modify them with blueprints to give them a toxic, electric, fire abilities and more. You also don’t have to be the zombie killer, you can join someone else’s game as the Night Hunter which is alternatively the mother of all zombies she has her own unique abilities like spider-manning around the map in order to reach online survivors.
I did not have to go this far explaining why it’s my favorite game but rather I had the intention to obligate others to try this game. Endless possibilities even after campaign completion.
