Warcraft Rumble Game Modes
The game trailer was just revealed, so we don't know exactly what all the game modes are or how they will play out, but this is what we currently know.
Player vs. Environment (PvE)
We know this game seems to have a heavy focus on PvE, just like the other Warcraft games. This kind of game-style has been seen in mobile games before, but they've all been heavily focused on PvP. That means this game's main appeal will be to a slightly different audience. That doesn't mean less competitve though!
The trailer announced a few things, such as:
We don't know exactly how all the game modes will work, but things like co-op will be super fun to use, probably for doing things like the Dungeons and Raids that will be in the game. It'll also be great to have that option to play this game with your friends.
Player vs. Player (PvP)
We didn't get nearly as much PvP information as PvE information, but Blizzard has said there will be PvP as well as a competitive PvP mode. We can expect things like Leaderboards where people who win the most matches are recognized. Blizzard does a pretty good job with their matchups, so you'll likely only play against people who are of similar character levels and skill levels.
There's been no word yet on whether or not we'll see some kind of co-op PvP mode, but with Blizzard's focus on PvE and the ability to play with your friends, it is likely we'll see one release at some point if not available at launch.
