The in game multiplayer interface for deathmatch supports buying and selling of items.
Characters names float above the characters as they play... allowing you to distinguish who's who
Object manipulation, including dropping and picking up items work correctly.
Characters can join parties, and share objects through their green 'swag bag'.
Kill stats are maintained in deathmatch games, and are displayed in the main game interface under the player's icon, and on the player list in the multiplayer in game manager screen.
Host Edit mode (or Host God mode) is displayed in bright red letters for clients when they select to play a game in the connect screen. This makes it clear to clients that the host has the ability to view and edit characters in that game. We considered removing this feature in the deathmatch game, as it was intended for MUD persistent games, but decided to retain it after testers requested it be kept in.
Character LAG is dramatically reduced.
