SlapChop

Geez everyone goes crazy. Anyways it should be working now. On another site I frequent they are reporting that everything is fine now. I had a slim PS3 so I never saw the problem but my friend with a 40gb fatty who texted me earlier crying about PSN was playing mag with me not 5 minutes ago. 
 
All is well crisis averted... until next leap year? 

They are pretty great changes. The L/MMG changes while hip firing are great. The shotty spread is great. Not being able to basically snipe with iron sight and red dot sights. 
 
But the biggest fix IMO is SVER not being able to remove charges through the doors. That stuff way really annoying. 
  
 
All the patch notes for those who care: 
 

Gameplay

• Overhauled tuning of multiple weapons of all types (see “Weapon” section below)
• Improved speed of weapon and gear swapping by approximately 500 milliseconds.
• Fixed bug in SVER’s Aralkum Mechanical Acquisition map and Absheron Refinery Domination map that allowed players to defuse a charge planted on a repaired gate or door.
• Added a “solid tone” sound effect near the end of a charge’s beeping detonation timer so that players know when the charge can no longer be defused and that they should vacate the area.
• “Medium Improved” Armor now works as intended with the speed properties of Medium Armor and a defensive value greater than Medium, but less than Heavy Armor.
• Changed resuscitated player’s camera orientation to match the last camera direction used while incapacitated instead of the pre-harm camera.
• Players no longer lose XP if a teammate is killed by an objective explosion caused by a charge they planted.
• Respec Point requirements in Barracks have been changed from 3K, 5K, 10K, 17K, 26K, and 26K-Repeat to 1K, 2K, 3K, and 3K-Repeat.
• Lowered the amount of damage necessary to kill an incapacitated enemy
• All fired projectiles (RPGs, Turret Rockets) have been given a steadier aim.
• Mines that haven’t been triggered are no longer removed from the map when the dead player that deploys them respawns unless that player changes their Loadout (note: The maximum number of mines you can plant cannot exceed the number you initially spawn with).
• Fixed bug that prevented “fully-resuscitated” players with more than 100 health points from receiving their full HP.
• Fixed bug that caused players to take unnecessary damage from both friendly and enemy vehicles when touching them.
• Players no longer lose leadership points after entering “Veteran Mode.”

Weapons

• “From the hip” firing for Light and Medium machine guns have stronger recoil and are less accurate when moving.
• Tuned weapon damage for all three factions.
• Modified all short-ranged weapons (pistols, PDWs, shotguns, SMGs) so that they’re less effective at long distances.
• Made Battle Rifles more effective.
• Reduced accuracy bonus for using iron sights and reflex sights so that players can no longer snipe with weapons that aren’t intended to do so.
• Increased damage values for all rockets to make them more effective (ex: three rockets can now destroy a DE turret).
• Shooting through thin materials (fences, tents, etc.) will be more consistent.
• Increased spread on shotguns.
• Improved animations for rocket launchers.

Graphics

• Fixed bug that caused the recoil animation to end early or stop animating if a player was firing their weapon for a long period of time.
• Changed detonation time on smoke and poison gas grenades to prevent them from exploding in mid-air to eliminate unintended FX issues.
• Added realistic fogging effects to sky-domes.

Technical

• Fixed most conditions that caused players to be caught in a “respawn loop” which kept restarting the respawn queue when the countdown clock reached 0.
• Changed in-game conditions to make it less likely to experience in-game freezes.
• Improved client-side stability.    

" Ok.... i have had a love hate relationship with this game.  I almost traded it in but decided to stick it out to level 10.   Glad i did.... currently it's in the awesome zone again. A BIG tip for the developers though.... i had to turn sensitivity from 30 something to 71 in order to enjoy this game. Tweak that and the obnoxious recoil (i fixed with upgrades) and newcomers will stick with your game.  Also i just read a post on Sony Blog where the developer says that newcomers love choosing the running fast into action role..... we don't LOVE it... we paid $60 to play a game, not a "walk to the action and get shot" simulator... we have no choice, the spawns are too far away.  Anyways maybe they know all this and it's a system to sort the wheat from the chaff.... only the truly dedicated will reap the rewards. "

It would be cool. The "lore" can just be worked out. It is the shadow war after-all.

Have you guys cleaned your ps3s out? They are the older models, maybe they're just getting a little hot? I sold my friend my 60gb and he is having no problems with mag.  
 
Just a suggestion wouldn't hurt to try it out.

Valor can also repair through walls. and some doors from the second floor to the first floor. 
 
Hopefully these will be fixed soonish.

-You can resupply from the bunkers. I once kept seeing my squad run to a resupply point FROM the bunker.

I got to 4th prestige in MW2. Since buying MAG I haven't even looked at COD.  
 
I also bought AC2 and Bioshock 2 and still haven't even opened then yet.  Also there are a few people that purchased the game and did exactly what you did during the beta. I have seen a few "MAG Played once not my type of game" ads on craigslist. So check there too. Also before going into it remember that until about level 10 you will most likely be completely lost. Stick with your squad.
