Xeno Crisis

Getting an S Rank means that you can only get hit 0 or 1 time during the entire level.

Below is a video walkthrough of my S Rank run through of The Lab along with some tips and tricks to make a successful run. Use Seed 1048 to get the same map layout as me.

Remember to use the debug and backer menus.


First of all, you will want to bring up the debug menu. On the main menu highlight Options and then hold down , , , and then . Make sure to turn on infinite ammo and infinite grenades. It would best to not turn on infinite health so you can tell if you have been shot. Also change the level to The Lab. If you want the same map layout as me use seed 1048.

Next you will need to bring up the Backer menu. Go back to the main menu and highlight Options again and then hold down , , , and then and choose backer 7 Jacqui. Also select The Lab as the starting area.

Make sure to change your difficulty to easy on the options menu.

Co-Op: I personally found that using the second controller trick that I used for my S Rank run through of HQ made the boss battle harder since the boss had double the health. If you wish to still use the second controller co-op trick below is a short explanation.


Some tips to make a successful S run.
- An S rank run means that you can only get hit once.
- When going through rooms always go up when you can get a chance. Side rooms tend to only have survivors and will have a dead end.
- To get quick kills against any enemy throw your grenade directly at the enemy. A direct hit will instantly detonate the grenade to kill the enemy quickly.
- Prioritize the gun turrets that shoot in all directions. Throwing a grenade at them and getting a direct hit will instantly kill the turret. There is a cooldown period between grande throws.In the event that you cannot throw a grenade you do have enough time to kill it with your gun, but you must start shooting it immediately. If you have a second delay you have the potential to get shot.
- Remember that the slow moving humanoid troops respawn if you kill them by shooting them. Throwing a grenade at them will ensure that they do not respawn.
- Always look at the floor to see any shadows. A shadow indicates that an enemy will spawn there. I had many failed runs because an enemy dropped on top of me.
- You can roll with , so if you are about to get shot try rolling away. Please be aware that if you are shooting it will have a second delay before you can roll.

Boss Battle
There are a couple of things going on with this boss battle. The boss turns in clock and counter-clock wise circles and spits out fire that will hurt you. You will need to run in the same direction as the boss, and look for when the boss stops and turns in the opposite direction. Make sure to run near the boss instead of hugging the wall. If you hug the wall while running you will not be able to keep up with the boss' rotation and will get hit like I did in minute 8:41. If you find yourself about to get hit rolling with can potentially save you. Also, the boss spawns gun turrets which can hit you really quickly. When these turrets spawn they should be your priority to kill.
