[Wicked Sid]

I'm a big fan of shovels as a melee weapon. A twisted minded person would sharpen the blade so it becomes a really wicked ranged edged weapon.
Sid, did you know you can go over to Amazon and build a Zombie survival list? Supplies, weapons, equipment, clothes... with comments. Kinda fun when you have the time.
Anyway, the colony is basically an enclave in enemy occupied land. Everyone should be carrying something for protection. The fact that they aren't points to Marcus losing sight of real problem.
Yes, we humans are basically lazy and selfish. Given the choice a majority of the people would choose not to work... BUT, if you cultivate a culture of hard work and communal integrity, you'll get people to put in the time. The whole Serf thing is too heavy handed.

But, not everyone is putting in their fair share. Why in the hell would they need supervisors? Its not a truly professional environment, and the Guardians seem like the only ones who should be able to stand around seeing as they protect the damn place. It really sounds more like a prison rather than an Enclave.

On another note, why do the supervisors need a taser? To put the people back to work? Why do they need to be put back to work? Drop your goddamn taser and put your share of the load on your own back. The Colony really seems like a counter-intuitive situation, treat them like prisoners, A.K.A. Shit, and they'll become pissed off like prisoners which all ends in revolt.
