I get that "Harder" is supposed to be more difficult than "Normal" or "Hard", but jesus christ, it's not even possible to win it, I've tried everything and every time it looks like you might catch a break it goes sour and some damn Zombie eats all your people.
It's fun to have a challenge, but when you don't even have a fighting chance, even after trying 10-15 times, it gets frustrating and eventually it takes away from the game, which is why I've revised my 5 star and made it a 4 star instead.
Just to specify for everyone, in I am Legend they have a disease, aka NOT Zombies.
In 28 days/weeks later, again NOTY zombies, they're "Infected" this defenition comes from Danny Boyle himself.
