Kumorii, I assure you I've always loved this game whenever I play, whether single of multiplayer, and want to request a few things which may or may not have been said but will hopefully make it even more enjoyable! :D
1. I'm not sure how many maps there are currently in game, but perhaps could you add one thats like a Park or something? Or maybe something like a prison or graveyard? That'll be great, hehe. Also, could someone tell me what maps are already in :P
2. Hidden items. Basically have hidden areas that contain hidden items that will give you a great advantage over the hoardes of Zombies ;D Maybe it could be perks, or a rare melee weapon such as a machete or Katana, or something special like a sniper hehe.
3. Rank Bonuses. I know that you can get better weapons as you rank up, but perhaps you could have it so that your guns increase in ammo capacity, say such as the Machine gun could go from 60 to 70 and max at 80? Not major changes but little ones that make people smile.
4. Customization. I know Customization is big this next update/pre-release but a small suggestion is perhaps you could individualise yourself, say me, Mullerm could have a M on my shirt thats Red or something? Or even a small logo such as a triangle or square ^^
5. Just a few support weapons but how about something like throwing knives? Or perhaps cluster grenades (these could be one of the rare weapons :)) or even something like road spikes that slows down zombies :P
Well that's all I've got folks, and I hope you enjoy reading and agree. It would be great if some of these would be implemented and I'm off to play more Feed as soon as it comes up ^^
