What did we do?
To ensure that players are playing the game as they should be, we've added lots of progression into the humans. As you know, humans start with leather armour, and can upgrade their armour to iron armour over the duration of the game. The thing was, getting full iron, food and a few golden apples was too easy, and once you had this, hiding was the only way that you could win. Not anymore!
So now we've added Diamonds. The catch is, that they only form half way through the game, which means that to stay alive, you're required to get iron, and upgrade to diamond half way through the game. This means at the end of the game, you may get this intense fight with the human in full diamond armour.
But Diamond armour is not much better than Iron?
You're right! If you were playing normal Minecraft that is. There are now huge leaps in the protection offered by armour in the game.
Armour also gets slightly weaker as the game goes on. If you weren't aware, Infection is a game heavily based around Maths. We use absolutely tons of calculations to ensure that the game is as close as can be. One of the calculations that we've added is that now, iron armour becomes weaker throughout the game, meaning that it becomes easier to kill someone if they don't get Diamond. As proven prior to the update, people will run away and hide in Iron armour, and this update will make it easier to kill them. And if you were wondering, if you're still in leather armour at the end of the game, you'll most likely be killed in one shot! And this is why Maths is important in life. ;)
