GET TO THE GREEN ZONE.
Reports of carnivorous, flesh-eating gerbils that kill and eat anything have been circulating across the internet. Now they've reached your suburban childhood town.
Your elderly mother is in the house just to the North. she's given you a phone call saying she loves you, and you know that the gerbils are slowly devouring her. You have no way to save her, let me just tell you that right now.
Your stats:
Sanity points: 100
Success points: 10
If any of these two stats get completely depleted, you fail and die. Success and sanity points are lowered at my discretion, and if you cross the defunct telephone wires between the tops of the buildings.
You can't go on the ground–it's lined with a fine film of gerbils waiting for someone to tear the skin off of.

The sewers are filled with unusual amounts of methane–this factor contributed to the sudden outbreak of these gerbils.
If you destroy any building, that's 40 sanity points off, because it's your childhood town. The same for one if you destroy them all.
In the building to the west, there's a weedwhacker.
To the northeast, your friend has a tattered copy of “A guide to conversational carnivorous gerbil.” You may be able to reason with these creatures if you pick it up–but it's stained with who-knows-what, and you know you'll only be able to make out the way to say “Explode,” “Command,” and “His/her.” These gerbils are known to be gullible, but they're still intelligent enough to have their own language and strategies.
Your inventory: A hand grenade and a pogo stick.
I will be grading this.
Good luck…you're gonna need it.
