: For the first time, worms can pilot tanks, helicopters, and mechs. These provide both mobility and high-powered weaponry, such as the Helicopter's overhead machine gun or the Mech's ground-pound ability.
: Players can unlock a vast array of hats, gravestones, victory dances, and soundbanks (including themed voices like "The IT Guy" or "Cyber-Goth") to personalize their squad. Game Modes
: Large structures are scattered across maps. Worms can enter these to find cover from overhead attacks. Importantly, the interior of a building is only visible to the worms currently inside it, adding a layer of tactical stealth.
: Includes a training mode, a structured campaign with 30 levels of increasing difficulty, and "Challenge" missions that test specific skills like jetpack navigation or precise grenade tosses.
