Interception

Interception is a vanilla-compatible 32-level megawad for Doom II released in 2013. It was named as a runner up at the 20th Annual Cacowards. In 2020 and 2021 several releases were made to fix map bugs, replace the three demos, and return MAP15 to its original form. In February 2024 version 1.7 made more map and soundtrack fixes, replaced the third demo, and updated over a dozen par times.

A sequel, titled Interception II, was started and, after a long pause in development, eventually released in August 2020.

In the far distant future, you are part of a team of marines, who are sent a distress signal from an archaeology site. Once you arrive, the rest of your team is killed by some nasty hell spawns. Now it's your job to stop the invasion, or die trying. Along the way, you explore ancient military bases, an underground necropolis, and Hell itself.
