at all this way.

Enter the underground area; either entrance leads to safe rooms. The doors open automatically.

The first bookshelf contains a medkit and ammo.

Proceed through the NE room, but do not enter the room with gas tanks. Instead, shoot the gas tanks from a distance to eliminate mutants inside. Entering the room will cause the tanks to explode, killing your squad.

In the next room, you will encounter Toccomatta, a mutant who speaks before dying. Loot his body for a letter and impact gloves. Another shelf holds more medical supplies.

The cafeteria presents a challenge. Position your squad within view of the doorway but not too close. Eliminate the melee mutant at the far end. Use grenades to deal with the second mutant hiding behind boxes. Be prepared for a mutant to emerge from behind the bar.

If the mutant behind the boxes moves back, the door may close. You may need to move your grenadier close to the door to open it and attack, being careful not to cause friendly fire. In turn-based (TB) mode, attempting to rush through may result in death if the mutant is on overwatch, as their flamethrower attack is lethal.

An alternative strategy for the cafeteria involves using a sniper to eliminate mutants one by one while a big guns character stands perpendicular to the door to mow down any mutants that charge the sniper. To defeat the flamethrower-wielding mutant, have the big guns character crawl across the floor to the bottom left corner, out of flamethrower range, and attack with a powerful weapon like a Browning M2.

The final room requires careful execution. In TB mode, move towards the door to open it, fire, and then retreat to close it. Alternatively, position a character with poor firing ability (like the medic) by the door against the wall. Move your other characters into position to fire, then retreat them after each shot. Gamorrin has 150 HP and will take time to defeat.

In Gamorrin's room, a holodisk containing Gamorrin's journals is located on the floor by a table. It is hidden by the angle of the west wall and may be difficult to see even when you know its location. The debrief mentions the Elders reviewing it, and it awards approximately 1300 XP.
