When you'll need to power up the energy cannon to make Gestalt vulnerable, you can take the plugs and just throw them into the sockets to get it done faster

Get ready to dodge a lot, try to keep your guns for the last 2 corpus of Phobos, as his last phase is super hard to melee hit without getting damage.

No Mercy: Gestalt 2

Defeat Gestalt once and for all.

Story Victory

You've beaten the Story Campaign! Well done!

Story Victory: Madness

You've beaten the entire Story Campaign on Madness Difficulty. Incredible!

For each level, you must beat it once in 'Tough' difficulty to unlock the 'Madness' difficulty

Use the phone booth to save time and check how you did in each level

Nexus City Map

Arena Achievements

Before getting started, you should know that you can restock your equipement and your allies's by pressing TAB during the intermission before starting the next wave.

Victory: Sleepwalker Program

You've completed the Sleepwalker Program.

Victory: Pit Stop

You've completed Pit Stop.

The West side of the map will group enemies until there are enough (around 6) to launch an attack. A good idea to prevent gas pumps from exploding is to always check there and trim their numbers to attacks

Enemies will also try to break the East barrier to launch attacks, this buys you some time and allows for easy kills as they are busy

Once you've completed Pit Stop, you'll be able to recruit Hirelings, it's highly recommended you do so

Hirelings can be commanded, and are a one of the main components of the arena mode, see more in this guideVictory: Foundry

You've completed The Foundry.

Victory: Fast Track

You've completed Fast Track.

Victory: Slaughter Time ™

You've completed Slaughter Time ™.

Your hirelings can manage to win this level by themselves in lower difficulties, here your objective should be to get as much XP as possible for the 'Acrobatics' skills. This means using only throwables (ex : axes, no explosives) , and throwing melee weapons to your enemies.

At the same time, this allows your Hirelings to gain lots of XP, so protect them by hunting down the green and red enemies

Victory: Haunting

You've completed The Haunting at Nevada House.

Victory: Murder Room

You've completed The Murder Room.

Victory: Hard Sell

You've completed Hard Sell.

Your main objective is killing the guys that are trying to unlock the box, once it's open it's almost always game over. In case you are overwhelm by enemies, prioritize your targets. The black guys that are going for the objective have to be killed or interrupted (ex: by shoving) first.

Place strategically your hirelings, they should always be able to shoot at someone in contact with the objective. See this guide to control your hirelings

Restock your ammo !

Don't chase the enemies to their spawn zones, you may miss others going to the objective in the meantime

Victory: Facility

You've completed The Facility.

This is pretty much the hardest level, your hirelings probably won't make it to the end, so make sure you have upgraded to the max 'Support Squad' in your base, so you can get some breathing room if needed

The last rooms can feel overwhelming, but if you correctly prioritize your targets it can become a lot easier.

Try to avoid killing melee enemies (shield dudes and big boys with hammers), as there is a pop cap of simultaneous enemies in the arena, the wave become a lot more manageable when there are only 2-3 guys shooting at you at the same time.

When a Mag appears, remove it's helmet and kill it as soon as possible, if you correctly did the previous step, there should be no gunners to bother you while killing the Mag, and instead a bunch of easy to evade melee enemies

Wave Completion

You've beaten all Arena Combat Waves! Nice.

Arena combat waves are : all helipad missions + the sleepwalker program (same for the next achievement)

Wave Completion: Madness

You've beaten all Arena Combat waves on Madness Difficulty. Outstanding!

By default, madness is unlocked after winning in 'Tough', but you can actually unlock madness mode by finishing in any difficulty, as seen in this guide

You don't need to play all waves in madness, you just need to complete one wave in Madness and then 'safe quit' to unlock the achivement (probably a bug)

I've Seen it All

Complete the Arena campaign three times, and collect three Imprints.

For the final story mission, try to save your ammo for the boss, or else get ready for a veryyy long fight

When you get to the final story mission, you'll be able to start from scratch with a new imprint, and all stats upgraded.

After the second run, the fastest class to finish the game again is the tinkerer, due to infinite money that allows you to just buy the best gear and craft amazing guns and rush
