This game is worth playing if only for the multi-paragraph outbreak explanation at the beginning. Seriously, read it. There’s science involved. And rats.
Once you get past the damn novel, you’ll find an enjoyable top-down game with simple RPG elements. Shoot zombies, level up, increase your speed, health, and weapon proficiencies, rinse and repeat. You’ll also be slaughtering the undead to such metal anthems as “GoreBastard” and “Demon Slayer12,” so you’ve got that to look forward to.
It’s not super deep, but Project Validus: Survival does serve as a nice distraction between TPS reports.
