A Trap

A Trap is the twenty-second mission in Earth Defense Force 2025 and Earth Defense Force 4.1: The Shadow of New Despair. It is the first mission to take place on the "Cave" map.

Objective
2025: The infiltration was a success. We were greatly outnumbered, so our casualties were high. The enemy is on familiar ground, after all, which gives 'em the edge. Expect an attack the moment you step inside the nest. Try to use the terrain to your advantage.

4.1: The infiltration was a success, but we're greatly outnumbered, so our casualties could be high. The enemy is on familiar ground, after all, which gives them the edge. Expect an attack at any moment while you're in that nest. Try to use the terrain to your advantage.

Storyline
This mission is the continuation of the previous mission, after Storm Team and various soldiers jumped into the giant insect's nest. It takes place in the same cave system where the EDF is trapped and has to defend themselves from the incoming attack.

The mission starts in a giant cave where one of the Rangers notes that the giant cave is a giant cave. Soon after he stated the obvious Ants will flood from the two tunnels at the top of the giant cave and attack the team. Soon they will be followed by Spiders and more Ants.

Once the final Giant Insect is dead HQ finally remembers that there is still an ongoing operation and decides to call in to order a retreat.

4.1 Changes
Just like all underground maps this level is dark. Also Depth Crawlers and SDL1 can be called by Air Raiders.

Both Versions
This is one of the harder missions in the game. The bottom of the cavern is very dangerous since the Giant Insects can attack from any side and can easily surround the players. The best bet is to find the slope going up along the walls to the top. On the top of the cavern there's a bridge connecting two tunnels on the opposite sides of the cave. The players should make their way to the closest tunnel, which will serve as an excellent chokepoint for the incoming enemies. There the usual tactics in tunnels will apply. Before going up it’s a good idea to grab the Wing Diver teams and make them follow the players as backup. The Ranger and Fencer squads can also be used, but they usually fall off the slope before reaching the top unless the players climb really slowly.

If the players fall down or are masochistic and decide to stay at the bottom, they should stay close to the walls to avoid being blindsided. The fact that in 4.1 the map is dark doesn't help, but certain weapons like rocket launchers can be used to temporarily light up the whole cavern.
