The game looks and feels incredible while you play. The mechanics are amazing and guns feel great, however it's virtually unplayable, especially if you're a single player person.
You quickly go from an area where's there little to no competition against a couple dinos, to an area where there's seemingly endless swarms of them where your bullets do miniscule damage, leading to your very quick death.
There's basically no upgrade system and no meaningful items to find to make you stronger (as far as I can tell), so the dinos quickly overpower you and you're practically helpless.
Also, the "boss" dinos seem like they take no damage and can kill you before you can even expose their "weak spot", along with their dozens of beefed up, armored friends.
