'So that's how it is,' Mathew thought when he noticed the changes on the golden screen displayed before him.
As soon as he attempted to add one point to his vitality statistic, two things happened.
First, a new panel opened up right in the middle of the display with a single number of five on it. Then, as soon as Mathew's eyes moved over to that new panel, a confirmation button appeared below the number.
'Five cores for raising a single stat by one?' Mathew thought, raising his hand to rub his chin. 'It's hard to say whether it's cheap or not...' he thought. 'Or is it?'
The only way that Mathew knew to level up so far, or rather, the only way that he could level up, was to kill more and more zombies.
And it definitely took more than just fifty zombies to raise his level by one and be rewarded with ten statistic points to distribute to his powers.
