Sectopods cannot be selected to be on your squad in multiplayer.
Many of the strategies listed in this article were formulated before the release of XCOM: Enemy Within and thus will not work as specified, they will have to be modified in order to be effective against Sectopods with their new trait. This, combined with the reduction of the HEAT Ammo bonus against mechanical units from 100% to 50% makes them one of the most significant threats in the game. In XCOM: Enemy Within Sectopods take 50% less damage from all sources, effectively doubling their health as well as the amount of damage repaired by any escorting Drones. While extremely powerful weaponry is required to reliably kill a Sectopod, these deadly machines are most definitely not invincible. The Sectopod's primary threats come from its very high health and its Cannon Fire ability which allows multiple devastating attacks in a single turn. It is often found aboard larger alien ships and during late game Terror Site missions. It appears around six months into the campaign (usually after researching Heavy Plasma) and is usually accompanied by two to three Drones. The Sectopod is an extremely dangerous robotic enemy.
