The download is less than one GigaByte. But you might want to skip it all together.
It's not an MMORPG. It's basically the Warhammer Online scenarios except with 3 sides (blue/green/red teams) with 6 players on each side. It going to use the F2P (free to play) model.
It's a simple game (the combat you mash one of 5 buttons on your toolbar with different abilities unique to each hero you control). You level up after each schenario, got to Level 4 after 2 scenarios.
It's the sort of game for people who want just Arena combat/scanerios. Nothing more.
