I stealthily climbed onto the roof of the school building, probing the air for Rachel's scent.

'She should be deep within the school building now, I just need to find her...'

[Ding. Host has upgrades available, would host like to view available upgrades?]

'Yes, quickly, I have a feeling something's gonna go wrong, but I hope I'm wrong.' I swiftly climbed through a shattered window at a speed several times faster than a human could reach then looked at the screen in front of my face.

'So I have enough points to upgrade one to the max, and a bit left over for whatever...'

'Okay, upgrade defense to the second tier, and put the rest in attack, I'd rather not be overpowered by anybody.'

[Ding. Host has reached the second tier of evolution in defense, would host like to commence evolutionary path to defensive evolutionary path?]

'Wait, so I could reach Tier 2 instantly? I don't need to meet the criteria of each one?'

[Ding. Host can evolve to the second stage of evolution immediately, however it is recommended that host strengthen yourself to the max before evolution.]

'Okay, I don't evolve just yet, how much time does it take anyway?' I asked while impaling a zombie that wandered into the room.

I dashed out into the hallway and rammed a zombie into the wall with my head.

[Ding. Point gained.]

I stuck out my proboscis and smelled/tasted the air, a lot of zombies, at least a few hundred still aimed the halls, and the darkness that the world itself was covered in gave me no reason to hesitate.

'The hunt begins...'

I rammed another zombie away and slashed it with my claws, gouging out a good chunk of it's brain.  

I threw the corpse into another unsuspecting zombie, then leapt and anchored myself to the roof, I ran along it, tail becoming a blur as I slashed the zombies as I passed by.

In my wars rang the ever sweet sound of notifications of points gained.

I came to a stop when I sensed a danger signal, on that made me hesitate.

Then an arm pushed through the ceiling and tore a hole on it.

Through the hole, I pair of savagely glowing green eyes met my gaze.

'Well, if I didn't know better, I'd say that zombies are evolving too.'

[Ding. They are evolving, same as you are, this one is a Tier 2 zombie.]

'Oh, can you repeat that, I don't think I heard you right, Tier 2, how?'

[Ding. Host holed up in the hospital, which gave other creatures a head start, but you aren't to far behind, host is ranked 2nd in the world.]

Then the ceiling buckled and a small figure fell through.

[Ding. User has encountered a dangerous situation, activate user interface?]

'It would be appreciated, so do it.'

'Well, shit...'
