Zombies bang the door ... then you wake up, what if you see zombies after you wake up? Go back sleep ah? lol

Use your cars, who needs guns when we have cars. Cars kill more people in Malaysia than firearms do. If we had zombies invading Malaysia, most Malaysians are clueless about firearms and would have no clue how to use them and that's a bad thing. On the other hand, MANY Malaysians are already bad drivers, get into accidents and almost run pedestrians over on a daily basis, and when everyone else on the road is a zombie, that's a good thing.

Or they could just eat your face while you stab them with what might aswell be a kitchen knife.

Obviously, if you're going to fight the living dead, any melee weapon you use must be able of severing limbs or crushing bones on the first hit. Which is why you use a VEHICLE as a melee weapon.

Thermite would be useful, toss a bottle full of it in a small IED and watch it melt through flesh bone and just about anything else it lands on.

Sure, if you can find a chopper with a rotor durable enough to slice through the hordes, with a powerplant powerful enough to do it and ofcourse you need to know how to fly one. Or just get a truck, stick 4-5 chainsaws to it and charge them.
