Thunder is the thirty-second offline mission and the thirty-sixth online mission in Earth Defense Force 2025 and the thirty-third offline mission and the thirty-fifth online mission in Earth Defense Force 4.1: The Shadow of New Despair.

Objective[]

2025: A enemy mothership has invaded the city. She is formidable, but if we can shoot it down the Ravagers will be dealt a great blow. The hopes of our allies across the world lie with this strategy and they have offered their support. The entire world has been attacked by the alien mothership fleet. We must destroy the mothership, but we'll have to deal with her escort. Focus on their defense squads first, then we can take down the mothership.

4.1: Enemy motherships have invaded the city! Though formidable, if we can shoot them down, the Ravagers will suffer a great blow. The hopes of our allies across the world lie wih us, so they've offered their support. We're all in this together, after all! We must destroy the motherships, but we'll also have to deal with their escorts. Focus on the defense squads first, then strike hard.

Storyline[]

The Tactics Officer informs the ground troops that since the Mothership is protected by a shield screen they have to be attacked from the ground. Storm Team engages the enemies escorting the ship, while it deploys its Genocide Gun and destroys half the city. Eventually as the EDF kills most of the enemies on the ground the Mothership send out a small army of drones. Once the drones are defeated it deploys its Cannon Panels and slowly flies away. Once every enemy on the ground is destroyed the mission finishes

4.1 Changes[]

The mission is set on a different map. More enemies and more allies spawn. There's slightly more radio chatter when friendly reinforcements arrives and at the end of the mission HQ will tell the ground troops that the mission was a failure since the mothership got away. On Hardest and Inferno difficulties gold ants also make an appearance.
