Call of Duty: Black Ops multiplayer details are, not surprisingly, thin on the ground at this early stage in development. But if you were to scour the official World at War forums you’d be able to find some interesting multiplayer tidbits (if you looked hard enough).
Treyarch’s Multiplayer Design Director, David Vonderhaar, frequents the CoD forums and has left some interesting nuggets of Black Ops multiplayer details amongst his posts. Some of the details Vonderhaar talks about strongly suggests that the firm will ditch a lot of the imbalances of MW2 multiplayer.
While they’ve tried having custom killstreaks for each class, that seemed to complicate the ‘purity and speed’ of Create a Class.
Consequently, it’s fair to assume that customizable killstreaks are all but confirmed.
At this stage in development, killstreaks stack and carry over if you die, but do not contribute to further killstreaks (hence eliminating the ‘camping for killstreaks’ problem of Modern Warfare 2).
Treyarch are not fans of Commando, the extended melee range perk in Modern Warfare 2, and it is unlikely to return.
They’ve tried a ‘manned’ version of the Sentry Gun killstreak, but weren’t fans.
We may well see a return to pistols as the only available sidearm, or perhaps a choice between pistols and launchers. Vahn and many of the team are not fans of shotguns and machine pistols as secondary weapons – it gives a player ‘too much firepower’.
The knife may well become a secondary weapon – although Vahn didn’t want to say too much.
Finally, don’t expect the nuke to return as a killstreak. Vahn says they are not fans of a game-ending killstreak
