Essentially this is what we have found in our play
General Game-play and Multiplayer Issues.
-Custom games when everyone is on the same server, basically we are all East Coast 1; seems to be fine.
-Local play both online and offline seem to be operating with no issues for verses multiplayer.
-Online campaign seems to be an issue, essentially not loading. (From other posts)
-Search restrictions on multiplayer seem to not be constraining matchmaking. (If you search for slayer only, you might get action-sack or griff-ball etc - From other posts)Online Verses Multiplayer both Ranked and Social, (after about 7 minutes the game goes completely bland)Players other than yourself will have the display characteristics as follows.
-No flare from enemy weapons other than the Spartan Laser, or sometimes rockets.
-No animation for grenades being thrown, and limited animation for equipment being thrown.
-No melee animation
-You will also see their joints and armor light up but no blinking or lightning effects when shields are depleted.Your character will have the display characteristics as follows.
-Will appear to shoot, reload, throw equipment/grenades just fine
-You will not know when you are being shot at other than your shields decaying
-Power-up pickups such as over-shield and invisibility will sometimes insta fill, or have no charging effectVehicles characteristics as follows
-Some vehicles are not able to be interacted with
-Vehicles will sometimes be put into "ghost mode" where they will move with player, both aim and normal mobility, and reward splatters if you kill someone with the vehicle when in ghost mode (From other posts)Please treat this post as a compilation so that 343 can be aware of issues instead of complaining about the issues you are experiencing.
