I think things would be exactly the opposite. If you make guns and ammo rarer, people will become even MORE paranoid about losing them. "I just spent 2 hours to find an M4 with 1 mag and 10 rounds, I REEAAAAAALLLY don't want to lose them." Or: "Man I'm glad I found this M4 with 1 mag and 10 rounds, they're super rare. Hey, I see a guy coming... maybe he has some ammo. BANG BANG!.. nope, just a can of beans. oh well." The only way to stop the KOS is to make scavenging easier than killing. If it becomes more work to kill someone for an item that you can find all day long, all of a sudden killing them for it is less important. I know that once I've got gear, murdering people for theirs becomes a non-issue. Making items rarer will only increase paranoia, increase gear killing, and will only promote server hopping.

Just you bro, I'd try plugging your keyboard into a different USB slot. If that doesn't work check to see if any of your keys are sticking. Reset your keyboard settings to default in-game... if all else fails, replace it.

I'm with OP, I'm getting a little burnt out too... on the Alpha. Yes there is very little point to the game right now. Other than scavenge/die/scavenge/die/scavenge/die there is zero point to this game RIGHT NOW. Once they start adding features like camps/bases where you can horde things and re-start there instead of randomly on the coast, or missions requiring player cooperation or making your way to a certain city to radio for evac. Point is, yes.. the Alpha is boring and pointless for gamers. It is meant to iron out bugs and improve stability/security. It's not meant for entertainment at this point, it is merely a byproduct right now. As it progresses they will shift focus to player entertainment. I'm burnt out of the Alpha, therefore I will stop playing for now. Will I stop playing for good? Unlikely

two way radios would work, but chances are people using them are already friends outside the game and are using a voice chat. How common do you think it would be to run across a random person and say "Here, take this two-way radio so we could talk to each other". Plus, with a two mile range, they'd be useless for splitting up. Plus batteries, plus bag space, plus anyone else with a radio listening... yeah, I'll stick to Teamspeak. Maybe not a continent wide general chat, but why not individual chat zones for each city/village? That way you can't spoil somebody's sniping spot, you don't have to hear about noobs breaking legs, but you could still use it to meet up with friendlies in a particular city.

Didn't know this, thanks. Can carry a spare M4 on my back

I think it would help, If you're able to talk to other people it actually helps with cooperation and meeting up. Right now it's just a bunch of scared people randomly bumping into one another and shoot first, ask questions later.
