Another Big Base Attacked is an optional EDF Side Mission. It is available immediately after unlocking the side missions from New LA.
Mission Summary[]
Aliens attacked and seized yet another EDF base. Hopefully they won't have killed all people here. You are trapped inside this base. The EDF are on their way but you have to hurry. Escape from the base as soon as possible and rendezvous with the EDF before they nuke the place!
Gameplay[]
It is important to know that upon entering this map, all of your set equipment will be taken away and you'll have to make do with resources the map provides.
Head through the door on the left. In on of the rooms, there's a platform above. Talk to the scientist behind the door and he'll give you a yellow keycard. Use it below. Take the elevator, make your way through the hallways and push a red fire alarm on the wall to create an explosion. Head downstairs and hit the switch next to a monitor to blow up the room. You will be submerged. Swim back and then crawl through a vent on the right side. Go to the big supply storage room, take out enemies, collect some goodies. Then proceed to the control room up the stairs and hit 2 switches to open a door to the outside. Dispose of aliens here (including battlelords), then find a lower area with octabrains and a green alien room. Scan the 4 combination switches with your PDA and unlock the green cage with a blue keycard earlier.
After taking the keycard and dealing with the "teleporting keycard squad", backtrack to the beginning and use the blue key. Follow the vent and hit the switch to unlock the forcefield. Backtrack and go through the door. Head through, jump over the damaged metal bridge and use a switch on the right to open a corridor. A red keycard is in the room to the right. Use it back in the earlier hallway. Eliminate several fat commanders and use the switch in the middle. Find an elevator and use it. Hop through the window opening, take out some protector drones, use the switch and take the train. Make your way to the outside and jump onto the bridge nearby. Make sure you run and jump across the bridge before it collapses. Proceed through a short cave and wait for an EDF helicopter to arrive. Prepare for an ambush. When you kill all the enemies, an exit will appear.
Secrets[]
There are 2 secrets in A.B.B.A.
- After blowing up the fire extinguisher to open a door, the hallway behind you collapses. While going down some stairs, shoot the discolored vent to the right to get some nice armour.
- Right before entering the control room, there is a security monitor that shows the forcefield next to the blue keycard slot. Right next to the monitor is a console, interact with this console, and the forcefield will deactivate.
Secret #1. The vent is already destroyed here.
Console that deactivates the forcefield
Secret #2
Collectibles[]
- Plasma Globe - located in the secret #2 described above.
- Alien in a Tube - located in the bedroom opposite of the one with the red keycard.
Other Items of interest[]
- In the outdoor area with the green cage with a blue keycard, hop on the metal ventilation shaft near toxic barrels to the right to get the speed item. From here, jump onto the metal grate balcony above the door to get a slot 5 weapon. Then, sprint and hop onto another grate balcony to obtain a slot 7 weapon. Also, a gold amulet can be found in the same area, near the green cage on the other side of the fence.
