Idiots. Using special type of energy sources hinders the enemies use of equipment they might get their hands on. Hopefully europeans are smarter. But.. ..note taken. I still think night vision is a bit off the top when it comes to zombie apocalypse. Not saying it's wrong, just saying it's not what I hope to see. And for the AK-47, it's ok. I think many czech gun cabinets have those. But not ACOGs and silencers. Or loads of ammo.

Achievements - When surviving a zombie apocalypse just ain't enough!

Agreed: The amount of items (weight) should affect your overall running speed and the distance one can sprint. This would make players really consider what they find useful and what they really need to tag along. So one can carry full combat gear with several weapons and tons of ammo and gadgets, but he ain't going to outrun a zombie without dropping some gear.
