Call of Duty: Black Ops II is set to feature a simplified multiplayer perks system that could see future restrictions without warning, according to David Vondehaar, Treyarch's multplayer designer.
Speaking to CVG, Vondehaar explained that addressing the increasing complexity of the perks system as the series continued was high up on the to do list.
"Perks were pretty important for us to rethink, because they were getting too complex, " he said. "You had perks, perk pros, perks that influence you, perks that influence your gun, perks that influence team mates.
"We've simplified that so perks only ever affect your character, and more importantly, Black Ops II's perks aren't absolutes. In Black Ops our only balancing options were to remove the perk or keep it; now we can tune any perk by increments to nerf it or improve it.
"I can nerf perks and I will, mark my words," Vonderhaar continued. "A perk should never be something you need just to compete. A perk is 'I got a parking spot,' or 'the soda machine gave me free soda.' Your life shouldn't depend on it. The community helped me understand that, and that's why our new system has no absolutes. We can try to make it the most balanced CoD ever."
Call of Duty: Black Ops II is out on Xbox 360, PS3 and PC this November and on Wii U from launch. If you're heading to this week's Eurogamer Expo, you'll be able to get your hands on it for the first time in the UK.
