Suggestions
Options: In addition to Mute and Mute All, please include, Mute Opposing Team (won't be activated until matchmaking has finished and the game enters loading), and Mute Non-Friends (will mute everyone except players on your friends list). It would be nice if you could permanently toggle these options on, instead of having to do it manually every match.
Auto Shoulder Adjustment: This needs to be put into the Control Option menu with default set to Off. Options are always good! Even though a lot of people hate it, some people probably like it.
Ticker: Ticker's current feed name needs to be anchored. i.e. Kills is displayed at all times, while the kill stats are moving by. Otherwise you just catch glimpses of numbers and have no idea what they represent.
Ticker: The ticker of stats is too slow, and needs to be sped up a notch. As well, it is fairly useless as only the party leader can see it on the main screen. It would be nice if it was available all the time on the menus until you get into a game, or at least until matchmaking brings all 10 players together.
Replay Options: More controls in replays. There is no Rewind, Step Backwards, or Slow Backwards. It is very annoying that you can only go forward, or to the beginning of the match.
Replay Options: Minute chapter markers on the replay time line so you can skip to the area you want quickly. It currently takes forever to get to the end of a 20 minute match even at 5x speed.
Replay Options: When the replay ends, make sure it stops at the end instead of automatically resetting. The user can manually go back to the beginning with the Restart button. It is annoying when something you want to see happens seconds before the match ends, and it resets all the way back to the beginning.
Medals: The Retaliation Medal is a good idea, but poorly executed, I feel. It should only achieved if you kill that person first after you re-spawn. As it is, you get them left and right just for killing that person at anytime. They should also not count if you get an Afterlife, as they currently do.
Medals: Competitive Medals on the website stats should not be displayed in Co-op page, and vice-versa. From a design stand point it does not make much sense to have them displayed as greyed out when you can not aquire them. It only made sense when they were not split into different categories.
Medals: A very minor niggle in that some of the new Medals are different shades of color, such as Tricky, Unlucky, Protectorate, and Tip Off, and this inconsistency is odd for such a high profile company such as Naughty Dog. Don't let this one keep you up at night, or take you away from more important things.
Medals: The new "Call of Duty" inspired medals have created many problems. Before they were on the right of the GUI and complimented the symmetry of Weapon/Clip on the left. Now the spot in the right is bare, completely throwing off basic design principles, and getting blocked by the scoreboard.
I used the scoreboard popping up as confirmation of death. Sometimes you can be in a really intense situation and think you're dead, the screen completely black and white, but you aren't, just sitting out in the open. Now with 1.06 you have the medals appearing and delaying the scoreboard and it throws me off. The whole idea of making the medals readable by delaying the scoreboard is pointless since it doesn't do that at the end of the match anyways. I believe there is no reason you can't have the new medal "system" while putting it back in the upper right where you can always see it.
My advice is to put it back to the right, to make sure the stats do not obscure the medal or cash value. If it isn't broke, don't fix it.
Custom Multiplayer Playlists: I think you should fire up GoldenEye 007 on the N64, and take some notes on mutliplayer playlists. Currently there is only RPG, Sniper/Pistole, Pistols/Grenades, and Crushing variants available for Deathmatch in Custom Games. Imagine .45 Defender only matches, AK-47/Pistol, Grenades only, melee only, GAU only, Wes only, Shotguns only, Hammers only, etc. It would be great if you could mix and match different weapons as well i.e. FAL+Sniper Rifle. We here at GAF really enjoy custom games, and try to make our own "rules" sometimes, but some people like to screw the rules over. *cough*Qlauragh*cough*
Characters: Female villains are a highly requested feature. Rika should technically be one. You have a large female player base, considering. As well, anyone using a female player on the Hero side has the disadvantage of being recognized as an enemy to the Villains.
Weapons: Currently Power weapons spawn in the middle of the map to make them balanced. However many people rush straight for them, and it gets old. I would like to suggest that they spawn in different locations. i.e. Where the Hammer spawns in Temple, the Rocket may spawn, the Desert 5, or the Shotgun. Each match would be random.
If by change you believe they should stay where they are, have completely random timers when they spawn in for the first time. ie. The Hammer may spawn in 30 seconds after a match starts, or possibly 4 minutes. The longest time it should wait is probably 5 minutes. Then it would be on the normal re-spawn timer.
If you think both ideas are great, combine them, by having them be in random spots, and random times, but shorten the first spawn time to 2 minutes and 30 seconds at most. Hopefully these ideas will spice up multiplayer at the beginning of a match.
Weapons: People like to camp the power weapons. I would like to suggest that each time you pick one up after the first time, it decreases in strength by 50%.
i.e. Rocket first time = 1 shot death. Rocket second time = 1 shot stun, 2 shots death, continue on.
Hammer first time = 1 shot stun, 2 shots death. Hammer Second time = 2 shots stun, 4 shots death, continue on.
This would possibly prevent repeated abuse of power weapons. I am very cautious on this suggestion, and just throwing it out there. If the previous suggestions are used, this one less important.
Treasure spawns: Every spawn 1-5 is predictable. They always spawn in the same pattern. It needs to be completely randomized. I would also like to see more and interesting places for it to spawn. There are plenty of interesting locations available in the middle of each map with varying heights.
