StarCraft 2's upcoming expansion, Heart of the Swarm, will retain most of Wings of Liberty's game balance while changing a few units and giving players more choice, according to the game's balance designer
Speaking to French video network, Millenium TV, StarCraft 2's game balance designer David Kim said that not a lot of the early game has been changed from Wings of Liberty except for a few units.
"We added a hydralisk speed upgrade," Kim said. "Ultralisk's have a burrow charge up ability right now and the battle cruiser is buffed a little bit in terms of damage. Oh yeah and the reaper changed. Those four things are the only things that changed.
"Some rules that we like to stick to for changing Wings of Liberty units is we want to mostly go for units that aren't being used much or that are a little difficult to use for different players, and we're looking to upgrade those things. We're not really looking to nerf anything until we go into the beta and realise that some unit, due to how new units work, become a little more overpowered."
Kim also said the game offers a ranked and unranked mode which allows more casual players to ease into the game while competitive players can access the ranked mode. He added that unlike Wings of Liberty, Heart of the Swarm will give players more strategic choices later in the game.
StarCraft 2: Heart of the Swarm does not have an official release date yet.
