Guerrilla Games has a team of six that do nothing but work on animations for the machines in the game. Visualizing these robots is one thing, but it is a whole other task to make sure they work within the game. "We need to make sure that things move in a way that makes sense, but also have enough clearance so that the things that need to happen in gameplay can," says principle animator Richard Oud.
Most of the time during the animation phrase, the team starts discovering what's fun and interesting about each machine. "Every robot has its moment where you find out its personality," Oud says. "For the Shellwalker, it was the first time he puts the crate on his head. His only obsession is protecting his cargo. When we did the first animation, that's the moment it started clicking with the whole entire character."
While the box certainly stands out, the Shellwalker has 150 unique animations to make him feel alive and react to various things that happen in the heat of battle. For instance, even if you shoot off the cargo clamp, he'll use his claw to secure his crate, giving him one less weapon to use against you. If you kill him and shoot off his precious cargo without destroying it, there's loot awaiting you. However, you never know what or how much is inside, making it a gamble.
