    The Martian Madness is a post-Golem invasion that can be done anytime after beating it. The event rewards the player with very powerful items dropped from its exclusive boss, the Martian Saucer. However, due to the great amount of powerful Martians that spawn the event can prove to be extremely difficult if attempted without preparation.

    The invasion will only happen when the Player finds a Martian ProbeMartian Probe in the wild and lets it escape into Space. The Martians will then spawn in areas close to friendly NPCs.

    During the invasion, all of the following enemies will spawn:

    • Gray GruntGray Grunts, the basic enemy of the event. Despite its simple appearance, it is one of the most dangerous martians due to its very high health and total immunity to knockback.
    • Ray GunnerRay Gunners, who behave similarly, but with lower stats and the ability to shoot lasers from their gun.
      • Occasionally, it will spawn riding on a ScutlixScutlix, becoming a Scutlix Gunner. The Scutilx moves very fast, deals high contact damage and its rider will shoot lasers, making this a deadly enemy. The Scutlix Gunner has a low chance to drop the Brain Scrambler (item)Brain Scrambler, which allows the player to ride a Scutlix of their own.
    • Martian WalkerMartian Walkers are a very fast enemy that can quickly shoot lasers, have a lot of health and are immune to knockback. Despite these attributes, their size and very low jumps make them prone to getting stuck on simple obstacles.
    • Martian DroneMartian Drones are small enemies with low damage and health. They will lock on to a player, and then quickly charge towards them before exploding.
    • GigazapperGigazappers behave like Gray Grunts, with lower stats and the ability to inflict the ElectrifiedElectrified debuff on hit, which causes a player to rapidly lose health when moving.
    • Martian EngineerMartian Engineers have low stats but instead of attacking, they can deploy Tesla TurretTesla Turrets, which shoot an electric projectile at the player, which inflicts the Electrified debuff. The Engineers should be killed quickly, as they can easily overwhelm a player with Turrets.
    • Martian OfficerMartian Officers spawn protected by a Bubble Shield, which will need to be killed before the player can harm it. If the Officer isn't killed quickly after the Bubble Shield is destroyed, it will activate again.
    • Brain ScramblerBrain Scramblers are similar to Ray Gunners, with their projectile inflicting the ConfusedConfused debuff on hit.
    • The Martian Saucer is the boss of the event. It will alternate between firing lasers from its turrets at the player's position, shooting homing missiles from its Cannons, and then following the player while attacking with its Deathray. Players must destroy the Turrets and Cannon first, as its core can't be damaged. After these have been destroyed ( any difficulty / Expert and Master only), the player will be able to damage its Core, and it will move more aggressively than before, and will only use the Deathray, which also does much more damage. When killed, it will drop a unique weapon or item.

    General Strategies[]

    General Tips[]

    This content is transcluded from Guide:Practical tips § Combat.

    • For nocturnal bosses, starting the battle just after the sun sets (7:30 PM) will provide the maximum amount of time to defeat the boss. In Hardmode, the Moon CharmMoon Charm and/or Moon StoneMoon Stone and their upgrades are also useful at night.
    • Boss battles can be won or lost before the battle ever starts. Choose your equipment and have it ready; find and/or make potions and placed buffs; use the highest-tier food you have available; set up an arena appropriate to the boss; learn the strategies for the boss you're facing.
    • Prepare your Boss-fighting arena with adequate lighting, CampfireCampfires and Heart LanternHeart Lanterns for health regeneration, and Star in a BottleStars in Bottles for mana regeneration if you use magic. Bast StatueBast Statues will provide a significant defensive boost. Garden GnomeGarden Gnomes and (if underground) proper torch placement will reduce damage taken and increase damage dealt due to the luck. Note Torch God's Favor helps with this. HoneyHoney pools can also be used for extra health regeneration.
    • SunflowerSunflowers provide the Happy! buff to players within a 50-tile radius, which grants a +10% movement speed bonus and 17% reduction in enemy spawn rate.
    • Always carry around a stack of the highest-tier healing potion available, as relying only on natural Health Regeneration is not a good idea. Depending on the game stage, this can include items such as Mushrooms or Honeyfins. On the Desktop version Desktop, Console version Console, Mobile version Mobile, and Nintendo Switch version Switch versions, Restoration Potions are healing potions with a shorter cooldown.
    • It is suggested to build houses for the DryadDryad and the NurseNurse NPCs in your arena. The former casts the Dryad's BlessingDryad's Blessing buff, which increases your defense and provides you with a thorns-like effect, while the latter can heal and remove debuffs instantly, at the cost of some Silver Coincoins.
    • Bosses are displayed on the Minimap: Follow the boss's icon to track it when you're struggling to find it. You can identify the boss icons by checking their respective wiki pages.
    • Once you have freed the MechanicMechanic in the Dungeon, you can use WireWire to enhance your arena with Dart TrapTraps and helpful Heart StatueHeart and Star StatueStar Statues. The former helps to damage the enemies, though be careful to set them up correctly in order not to hurt yourself during the battle. The latter will spawn heart and star pickups, respectively. Connect these devices to 3 Second Timertimers.
    • It may be useful to summon and kill the Eye of Cthulhu or King Slime before summoning any harder boss in order to spawn an extra one-use pool of Hearts. Note that this will prevent any Heart Statues from spawning new Hearts.
    • Remember to use the Sharpening StationSharpening Station, Ammo BoxAmmo Box, Crystal BallCrystal Ball, Bewitching TableBewitching Table, and Slice of CakeSlice of Cake before you go to explore or battle bosses/invasions. These will give boosts that are useful to take, with the first four being class-specific. They give SharpenedSharpened, Ammo Box (buff)Ammo Box, ClairvoyanceClairvoyance, BewitchedBewitched, and Sugar RushSugar Rush, respectively.

    Terrain Preparation[]

    The event was easily exploited until 1.4 by standing in a box above the ground.

    The great amount of enemies with high stats and/or projectiles makes it very hard to survive the invasion in the open. The event is better fought around your base, where the martians will be much less likely to overwhelm you with projectiles. Make sure to protect your NPCs however, as the enemies will easily kill them.

    Like many other invasions, all pre-1.4 enemies completely lack the ability to attack through blocks, as only explosions from the Martian Drone and Martian Saucer have the ability to do so. This can be exploited by safely killing the enemies inside a tall box above the ground. Additionally, a pit with a shallow layer of Lava and Traps can be built to trap the Martians and kill them safely. Using Summon weapons you can safely and quickly beat the Martian Saucer from inside the box, and you can use Track since enemies cannot spawn on it, which serves as a great way keeping non-flying enemies at bay. You can also hop on the Track if you have a mechanical cart due to its great speed. Recommended weapons are the Tempest StaffTempest Staff, Deadly Sphere StaffDeadly Sphere Staffand Raven StaffRaven Staff. If you have a Xeno StaffXeno Staff, you are able to use it for the rest of the fight.

    You can still do it in 1.4 but you need either a Rod of DiscordRod of Discord or a Hook of DissonanceHook of Dissonance to teleport out of the way of the deathray.

    Note that the Martian Saucer will not fire its deathray through some blocks as long as the player is not under them.

    Gearing Up[]


    • For Melee characters, the Beetle armorBeetle armor is the best available. The Beetle Scale MailBeetle Scale Mail is better for offensive bonuses, while the Beetle ShellBeetle Shell is better for those that can’t avoid taking hits frequently.
    • For Ranged characters, the Shroomite armorShroomite armorShroomite armorShroomite armor is the strongest available.
    • The Spectre armorSpectre armor is the strongest for a Mage. The Spectre HoodSpectre Hood should be used only when at low health to maximize damage output.
    • A Summoner should summon their minions while wearing Spooky armorSpooky armor and then equip Tiki armorTiki armor for an extra, although weaker minion and slightly higher defense.


    For Melee users
    • The SeedlerSeedler or Terra BladeTerra Blade are both very good all around swords. If the Old One's Army has been defeated, the Flying DragonFlying Dragon is excellent against crowds.
    • The Paladin's HammerPaladin's Hammer is very useful for crowd control, and useful against the first phase of the Martian Saucer. The Possessed HatchetPossessed Hatchet makes a good combination with it, as it can deal with single targets and the second phase of the Saucer.
    • The FlaironFlairon is very powerful due to its many high damaging bubbles.
    • The Eye of CthulhuThe Eye of Cthulhu is the strongest yoyo available until the Terrarian.
    • The Vampire KnivesVampire Knives are a strong weapon with lifesteal capabilities.
    • The Scourge of the CorruptorScourge of the Corruptor has low damage, but many homing projectiles.
    • The Death SickleDeath Sickle can pass through blocks. It is useful if the player has trouble dodging enemy attacks.

    Specific Strategies[]

    Circle and Shake (Expert/Master)[]

    In Expert and Master mode, you have access to a flying mount from killing either Duke Fishron or Mourning Wood.

    When a Martian Saucer appears, it will cycle through three attacks: shoot rapid lasers to the side, shoot homing rockets, and shoot a downward laser.

    For the first attack, stay above the saucer. As it releases the homing rockets, circle down and underneath it, coming up on the other side and dodging the rockets. This means that you'll be flying up and away when the downward laser fires.

    After it loses half its health, it begins aggressively chasing you, too fast to escape unless you're using Shrimpy Truffle with the water/rain buff. Instead of running away the whole fight, only flee until its laser turns off, then go in the opposite direction. It will fire and chase you again, but once the laser turns off, go in the opposite direction. Once you get the rhythm down, it becomes a much easier fight.

    Watch out, though, as burning Saucer Scrap projectiles fall from it as it fires. These do minor damage, but can knock you into the laser, so it's recommended to equip knockback-cancelling accessories like the Cobalt Shield or the Hero Shield. Also note that projectiles only land on solid blocks and fall through platforms.
