A guide to Chaos Rooms

This won’t be an in-depth guide about Chaos Rooms (otherwise there would appear the different enemies and all… Maybe in other guide), just a summary of points about the current rooms, intended for newcomers and those who go in them without knowing what will they found. No, this guide is not meant for getting high scores, but to complete the mission.

First, we have four easy points to do:
1. Use a robot commando you are comfortable with.
2. Remember to bring weapons with much ammo.
3. Did I say to be very careful about the ammo?
4. The most important point: you are here to win. Not the titles, not the points. You want to finish the mission. If not, look for other guides (this or this, for example. By the way, thank you for them, LazFlamme).

Now we will see what rooms we can enter, the attacks from the bosses, and other important points of every stage:

-Goten Returns: If you have done the Ouka mission, you know Goten, that enormous samurai-like bot. First you must deal with six enemies, three at the top of the map and other three below, taking the central fort as the center of the map (thanks durrp). These have wings, guns, and will attack you on sight. Not so dangerous (be careful, they have rocket launchers), but take care, because they can score some painful hits.
Once they are out, you will see a short cinematic, in which both Ouka and Goten show up. Now your main target is Goten. Forget about the other little -and not so little- ones, and concentrate all your firepower on Goten.
For Fly users, you can use the central fort to gain height advantage (again, thanks durrp).
Goten has three attack patters: he swings his massive sword in close quarters (avoid it running around him), launches a shockwave (first he lights a red flash, run to his flanks), or runs (lights a blue flash, then disappears in the direction he is facing, and finally a blue energy arises from the route he has followed; just do not persecute him directly and run along his flanks).

-Commander Operation: No, you won’t be facing K-Ogre. Instead, you will fight against Tycoon Buutak, his minion.
The first thing is to wipe out the big enemies with capes and a wheel-like thing in the back. They use a beam cannon and a great sword, so take care. Until they are destroyed and you see a cinematic, Tycoon is invincible, so do not bother attacking him. Once done, you will see a cinematic, and the real fight shall start.
When Tycoon is vulnerable, get him with all you got. He has four attack patterns: a flaming charge (surrounds himself in flames and charge ahead, if you get hit you can get the In Flames status; avoid by running to his flanks and/or back), a dark energy surging explosion (he stops moving, take a stance and then a series of purple explosions hits the surroundings and apply the Slow condition; avoid maintaining some distance, standing in high altitude or reach tall objects), an energy beam (the same stance he uses with the dark energy explosion, but this time focusing in a wide energy ray; avoid running to his flanks and back; it applies the Shell Drain condition), and a missile shower (shooting a missile barrage from his arms; avoid moving around).
Edited: the enemies with capes, before destruction, drop a number of silver coins, each worth 100UC, and the big ones, those who shoot missiles and have an aditional pai of arms with swords drop some copper colored, each worth 5UC. They are easy to get, but remember that the enemies will not wait for you to end the harvest to attack you. The best way to end the mission without problems is to ignore the money, destroy the enemies and make Buutak vulnerable, otherwise you will be offering your back for surprise (and painful) attacks. Then again, if you want to get extra UC, go and get it... But please, do not blame others if you are surrounded and end up dead. (Thank you for the info, LazFlamme)

-The Figure Named [the Chaos]: This is it, here your enemy is K-Ogre.
Initially, there will be some Chaos Ports, strange looking floating things. Destroy them first! Until you do, K-Ogre is invincible, so don’t waste ammo trying to kill him.
Once the Ports are done, after a short cinematic, the real fight begins. Try to avoid the rest of Chaos robots and hit him with all your power.
K-Ogre has six attack patterns: A rain of missiles (like Tycoon Buutak’s attack, but launched from the wings; avoid by running around), an Energy beam (as Buutak’s one; avoid by standing at the flanks and back), a fire ring (he stops moving, then moves the arms and release a short range fire-like ring; avoid by standing at some distance from him), a series of sword hits and swings (just go around him, or remain at some distance, preferably the last), a red energy ball (a big, red homing energy ball able to pass through walls, which applies the Slow condition if hit; It is very slow, so if it starts pursuing you, try to run away until it disappears), and a spread shot (shot in front of him, two lines of three green bullets, applying Slow if hit; avoid running to the flanks).The beam and the sword swings apply the Shell Drain upon impact. Avoid them at all cost, for it remains for some time, and if you rely on ammo (case of many Art bots), you can be left dry.

-Chaos School Invasion: The objective here is to repel the invasion.
In the first step, just wipe out enemies, cleaning the floors one by one. Once empty, some enemies will appear at the rooftop: various normal delgons, four Chaos Ports, one at each corner of the rooftop, and two winged delgons near every Port. The winged delgons are invincible until all four Ports have been destroyed, so don’t waste ammo on them until all the Ports are out.
After a cinematic, Delgonov will plant himself in the balcony over the entrance, bombarding you while his minions attack. Forget about the minions, and shoot at him until another cinematic activates. He will use an attraction ball (a purple energy ball; just run against it) and a bombardment with bazookas (run to the sides and continue shooting). Sometimes he will launch a big fist attack, just go to the opposing side or retreat a little to avoid it.
Ok, here comes the trap: obey Rouche every time you hear the alarm, and empty the hallways! Every time the alarm sound, a series of laser grids will sweep the corridors. If you are hit, you will be killed instantly (maybe not if enough health, but nearly death at least). Search the school for the new Chaos Ports and destroy them, always running from the lasers. You may come near Delgonov, but right now he is invincible, so do not waste ammo on him (be aware of the lasers, they stop near the stairs, and I have seen more than one player hit by them because they were a little too far).
Okay, once the four Ports are destroyed, a new cinematic will show up, and the final battle begins. Delgonov will be on top of the rooftop, and has only two attacks: a repulse ball (a yellow energy ball surrounds him, repulsing every near robot) and a missile barrage (launched from the satellite-like delgons that accompany him). If you have long range weapons, ignore all and shoot endlessly. If you are more suited for close range, use the wind tunnels to make several passes near him. Continue the attack and he will be done for.

-Return from Hades! : Here you mission is to destroy the phantoms. But this is far easier said than done.
The first point is to destroy all the ghosts and skullroids. The ghosts can fire a beam bullet, and the smaller and medium ones like to head butt any nearby player. Just take care and eliminate them.
After that, two great phantoms shall appear. Ignore them for now, because there are four Chaos Ports; until the four are destroyed, they will be invincible. As a side note, these Ports are far more resilient than the ones from other Chaos Rooms. You will need to focus on one at a time to put them down.
Okay, with all the Ports destroyed, it’s time to kill the great phantoms. They are just like the small and medium ones, head butting and firing a small beam bullet, but more powerful. If the phantoms are vulnerable, and you are low of health, look out to the tree line on the edges of the map. The phantoms will be unable to reach you with the head butt attack, but the beam gun can still hurt you.
Always pay attention to your map, and expect surprise attacks from respawned monsters. Here the main problem is the number of enemies. Remain calm and do not let them corner you.
For those who use melee, the great phantom’s head butt can easily overpower you, and they are immune to shock and stunlock (thanks durrp). Be careful if your melee bot can't use Crimson Veil (which makes you immune to stun). If you have no ranged weapons, always keep an eye on your HP bar, and retreat when it becomes red. And when you retreat, do it fast, because the phantoms are fast too (and please, as noted by durrp, try to run to the trees or to the building first, if the phantom chases you to a healing group it can be disastrous).

And now, some tips and helps:

-The repulse ball of Delgonov affects all robots, but not bits. If you have Pillbox Unit, Sniper Unit, and other bits that create a weapon, place then near Delgonov, so they attack him even if you are blowed away.

-There are some classrooms in Chaos School Invasion that contains destructible desks. You can obtain from them Shell Supplies, Health and other items. THIS PLACES ARE UNIQUE, AND THE DESKS DOESN’T RESPAWN. Try not to waste the items, specially the Shell Supply ones.

-When Chaos Ports are present, try to concentrate your firepower on one at a time. Take specially care with the Hades ones, as they are more resilient and regenerate health over time, so if not destroyed, it can recover the damage, so your attacks (and ammo used) shall be in vain.

-Your death hits the group, just as in the Arena. If there are many people, you can afford some deaths. But if the group is small, every death is a direct hit to your little battle points. Even if you are out of ammo, try not to die. Do not hesitate and retreat for healing if there are healers, if not try to be useful without risking recklessly. You can let the K-Ogre slow ball to persecute you to get it away from other players, or let the small phantoms from Return to Hades! chase you and lure some of their shoots.

-A last thing, no, FIREPILLARING TEAMMATES AT THE START ISN’T FUNNY. You may think it’s not a big deal, but if the affected can’t react in time, they can end running wild, or even right into some enemies. The same applies to Wind Tunnels (and the Wind Tunnles created with Feng Mei and other bots), please, be careful with them. Maybe the normal monsters aren´t bosses, but you can die both from a Buutak’s missile and a Delgon’s bazooka. And, in small groups, EVERY DEATH COUNTS.



Remember: you are fighting along with other players to complete the mission. If all you want are points and titles, the best way is to exterminate as much enemies as you can, and deal as much damage as you can. But this way, you will spend so much ammo that would be better used on the boss. Sure, you can use a Shell Supply to replenish your weapons, but remember that each bullet not fired at the boss/Port/miniboss won’t harm him, so you won’t be near victory, and the more time you spend, the easier it is for someone to die, the more battle points you will lose, and the nearest the team is to lose the mission.

You forgot to mention that in order to win in Commander Operation, AVOID THE MONEY AND CONCENTRATE IN DODGING THE ENEMIES WHILE RETURN FIRE. If you go after the money, you actually earn them, but it'll also restrict your path, and may lead you straight into any enemy. If you're unlucky, you'll face certain death from Tycoon Butak even before the Chaos Ports are destroyed.

Ignore this if your primary purpose in this room is to farm money. You'll doom your comrades this way, though.

Added the money fact (totally forgot about it, I was too busy trying to survive).
Thank you for the additional info!

Quote :

First you must deal with five enemies.

There are actually six of them; three on top, three below. If your team comprises of mostly AIRs, it's recommended to strike the ones on the upper half of the map first, so that after the cutscene they could take the height advantage of the central fort (assuming they have brought their flight extending abilities with them) before tackling Goten.

Quote :

four great phantoms shall appear

There's only two of them. They are also known to be immune to shock effect and stunlock, so meleeing them without CV and a healgroup nearby will only do more harm than good. And harm amplified if the said derp melee retreats to the nearby healgroup with the giant phantom on tow.

Added the new info, changing the previous five for six enemies, and the four phantoms reduced to two.
Added the fact of the height advantage, the CV (Crimsom Veil) and the immunities of the phantoms, too.

Thank you durrp!
