hello? you can buy specs with GP, it's not just for nx noobs. they didn't ruin the game, they made it better.
and chainsaw would be useless if people have guns in OMA, not to mention it would be heavy and have a delay to start it up before you could kill anyone.
but i thinkn that's actually a good idea, watch nexon still it from us.
and it wouldn't kill zombies in 4 hits, probably a bit more like 15. but it's most likely be based on how long the weapon is in contact with them, not how many times you hit them.
