Complete Guide for Alien Breed 3: Descent

Part 1 - Subersion

This Guide will help you get all achievements in one run

The logs are found in the Video at around 7:35 - Log 1/3, 13:50 - Log 2/3, 21:50 - Log 3/3 and the first secret can be found around: 28:20 - Secret 1/5


Log 1:Follow the mission objectives until you reach the point where you need to follow the way-point towards the Gyro. Keep an eye out—the log is located right next to the spot where the first enemy bursts out of the ground.

Log 2: Follow the objectives until you reach the point where you need to lower the water level to access the coolant room. Once that's done, follow the path and explode a couple of red canisters. Behind them, there's a glass window—break it and go through. The second log will be on your left.

Log 3: After rebooting the Gyro, head into the next room. The log will be on your right.

Secret 1/5 - After using the Air Supply Pressure Valve, follow the waypoint until you see a short cutscene with a container falling out of the window. Enter the room where the container used to be, and you’ll find the first secret there.

Part 2 - Re-Entry

The Second Secret can be found around 9:15 - Secret 2/5 in the Video Above, the logs are found as follows: 11:45 - Log 1/3, 24:45 - Log 2/3, 33:20 - Log 3/3


Secret 2/5 - Not far into the level, you'll enter a room with two electric circuits sparking above. To progress, you must deactivate the Air Vents, triggering a 1-minute survival battle.
After the countdown, exit by crossing the now lowered fans. Instead of going right, head left into ventilation tunnels where you'll spot red canisters, detonate further.
Return to the room with the electric circuits. A new passage is now open in the exact opposite site where you lowered the fans.
The second secret in the game awaits just down this tunnel.

Log 1/3 - Facing the wall with two electric currents in the room behind it, turn left to spot some flammable canisters that you can detonate. Inside this small room, you'll find the Log.

Log 2/3 - After navigating through the first vacuum section in this level, proceed across two bridges and enter a room centered around a power node. Activate the consoles to raise a bridge necessary for advancing. On your right, in the room directly across from an Intex Terminal, you'll find the Log.

Log 3/3 - After navigating through the second vacuum section, take the elevator up. Enter the shower on your left, where you'll find fire canisters that can be blown up. Inside the newly revealed tunnel behind them, you'll discover the Log.

Part 3 - Determination

- Tank - Take 500 damage on 'Determination' single player mission without dying
Don't forget about this achievement; it unlocks after you've taken 500 damage. So, don't worry about getting hit—if you can afford it. Even self-inflicted damage from the environment or grenades counts toward this achievement.

The Logs can be found in the Video above at around the following time stamps: 2:00 - Log 1/3,
30:25 - Log 2/3, 34:15 - Log 3/3 and the secret can be found near the end, around: 51:20 - Secret 3/5


Log 1/3 - Right at the start, this Log is in the room to your right.

Log 2/3 - After traversing through a long tunnel on the Cargo Platform, you'll cross a bridge and descend via an elevator which is shortly destroyed. You'll find this log to your left on walkways submerged in water—it's hard to miss.

Log 3/3 - You'll need to turn two valves to lower the water level and activate a console. After a cutscene, you'll find this log right where you land.

Secret 3/4 - Towards the conclusion of the level, a countdown will commence, giving you only 10 minutes to reach the exit elevator. Upon reaching the elevator, don't use it and proceed onto a nearby walkway where you'll notice some fire canisters that can be dislodged.

Dislodge the canisters and return to their landing spot. Detonate the canisters, retrieve the Storage Room Key-Card, and utilize it on the nearby panel to unlock the door and obtain the hidden item.

Part 4 - Vengeance

Exterminator - Kill 1000 aliens in single player
This achievement should have unlocked by now, or it will unlock during this level.


Immobilised - Stun 10 aliens with one Stun Grenade
You only need to stun 5 enemies, not 10. If you haven't unlocked this achievement yet, the best place to do it may be near the bridge, around minute 9 in the video above.


Frag-master - Kill 10 aliens with one Frag Grenade
You only need to kill 5 enemies, not 10. If you haven't unlocked this achievement yet, the best place to do it may be near the bridge, around minute 9 in the video above.


More Speed, Less Haste - Complete 'Vengeance' single player level on Veteran difficulty in 17 minutes or less ( It can be done on Elite Difficulty too )
Now this is more tricky, I advise to stack up on ammo and items from the previous levels and give it all you got


On this Map there are only 2 Logs, the first can be found around 1:40 - Log 1/2 in the video above. The secret is around: 10:10 - Secret 4/5 and the second log is around 13:15 - Log 2/2


Log 1/2 -At the start, move until you reach a dead end. Soon after, an elevator will rise up for you to board, with the log conveniently placed right beside it—impossible to overlook.

Secret 4/5 -At the halfway mark of the level, you'll encounter an Override Console positioned next to a Key Card Panel. To access the secret area, activate the Override Console. You'll have a tight window of 5-6 seconds to reach the locked door on your right.

Log 2/2 - The Second Log will be next to Barnes' body, shortly after you unlock a door with a Key-Card. It's located in an open area to your left. You can't miss it, as you'll need to use another Key-Card on a door next to him.

Part 5 - Resolution

The Informed - Collect all the logs throughout the game
This should unlock after fighting the Alien Queen for the first time


Hidden Treasure - Find all secret collectibles
This achievement will unlock randomly at some point during the level, not necessarily when you collect the last secret, so there's no need to worry about it.


Battle-hardened - Complete all single player levels 1-5
This should unlock when you finish the level


Elite Unit - Complete all single player levels 1-5 on Elite difficulty
This should unlock when you finish the level


The First and only log is in the Room Directly behind you at the start.

For the last secret, after defeating the Alien Queen for the first time and activating the Console, go left and use the elevator to ride up, you will find the last secret there.

Survivor

Survivor - Stay alive for 8 minutes on any single player Survivor level
This one took some practice, but I found that running around and shooting with the Electro gun seemed to work best for me.

Multiplayer

Time to Party - - Complete 3 Co-op Assault multiplayer games
This may also unlock during Single Player


Seasoned Squaddie - Complete any multiplayer level
This does not work in Multiplayer Survivor games


Meat Grinder - Kill 250 aliens on any multiplayer Survivor level
This achievement requires some trial and error. Only the host can earn it, and weapons respawn roughly every 30 seconds. The game starts when both players jump down. Find a good spot with minimal entry points is the best way. From there, the host should be able to rack up enough kills in about 10-15 minutes from a strategic camping position with ample ammo, while Player 2 keeps the side secure.
