Caleb Campbell was a supporting character in Dead Space: Aftermath. He was the captain of the USG O'Bannon and was in charge of the mission to recover the remnants of the Red Marker from Aegis VII. He was voiced by Graham McTavish.
Campbell and his crew of the O'Bannon set out to Aegis VII to find shards of the Red Marker. However not long after reaching Aegis VII, the landing crew encountered difficulty with the stabilizers overloading, which was made irrecoverable by Nickolas Kuttner, forcing the landing crew to abandon the planet as it started to break up.
He had attempted to get the O'Bannon further away from the planet to get clear of the planet's gravity well to shock out. But was too late as the ship was caught and damaged much of the ship's systems, including its Shockpoint Drive, leaving them stranded and at the mercy of planetary debris.
When Nolan Stross attempted to warn him of the Necromorph outbreak, he had been busy talking with Alejandro Borges concerning the Shockpoint Drive thus ignored Stross altogether. He along with two security officers were able to survive long enough to meet up with Stross, Isabel Cho, and Nikolas Kuttner. But as they made their escape into the vents, the Necromorphs overwhelmed the last of the security officers. Campbell, Kuttner, Cho and Stross fled into the vents and made it to Stross' lab, where they met with Borges, and two officers from the bridge. There he asked Stross to explain what was happening on the ship, and after learning that destroying the shard could stop the Necromorphs. Borges suggested that throwing it into the reactor core.
Debris from the planet causes a hull breach, damaging the outer door control for engineering. Captain Campbell sacrifices himself to seal the door manually then uses a grenade made by Borges to blow himself up and a group of Necromorphs surrounding him.
