Impossible disasters are supposed to be a harder version of both Hyper Disaster and normal versions of the disaster. Every reward for an impossible disaster is 2x the normal one.
While called "Impossible Disaster", they are not necessarily impossible. With the correct strategies and skills, each disaster can be survived.
|Spiked Walls||Difficult||The spikes will become extremely long - however, there are two walls instead of four (unlike its hyper counterpart). The walls now close in much more, moving in small increments every second or so. Players must find space in between two spikes with very little to no room to move around.||286|
|Get Down||Difficult||The kill brick comes immediately and is even lower than its hyper counterpart. The kill brick also lasts the entire round. Players need to get to the lowest parts of the map to survive.||308|
|Zerg Lurker||Extremely difficult||Spikes attack at a very fast rate and can detect and reach players on really high ground, higher than the house. Spikes will also stay up for 5 seconds instead of going away immediately.||396|
|Murderers||Difficult||Instead of moving around the map, they follow the players. They also can throw the knives quicker. Their knives ricochet onto nearby players once one of the knives kill a player that's nearby them.||429|
|Guest Ambush||Extremely difficult||Guests are faster. In addition to deleting parts, guests can now delete the player's arms and legs, along with whatever gear they happen to be holding (if any). Gear not held in the inventory are not deleted. Deleted gear will return if the player dies or resets.||220|
|Death Trampoline||Easy||The trampoline is considerably higher, reaching the height of Rising Lava's highest height.||231|
|X-Bomb||Insanely difficult||The bomb is taller, the beams are denser, and it strikes both X and + ways while spinning.||242|
|Mine Spawn||Difficult||Blast radius is increased heavily. Acts the same as Normal/Hyper(new) Mine Spawn.||264|
|Press The Button||Insanely difficult||Similar to Hyper counterpart, but the safe zone is much smaller (the diameter of the button squared). Disaster time is also shortened.||330|
|Slenderman||Very difficult||Its damage area is much wider and he is much faster than its Normal and Hyper counterparts. Can, at most, deal 40 damage per second.||264|
|Missile Strike||Difficult||Instead of aiming at the house, it aims at a random spawn point (enemy spawn) on the map.||297|
|Explosive Noobs||Difficult||The Explosive Noobs, now called Flying Explosive Noobs, receive the ability to fly with a bigger explosion radius.||297|
|Tsunami||Difficult||The tsunami is even higher and is faster than its hyper counterpart.||312|
|Ghosts||Moderate||Ghosts now deal ~20 damage, and move faster. They also stay invisible the whole round making sneak-attacks easier.||253|
|Shurikens||Easy||Large Golden Ninja Stars fall from the sky with much more speed compared to its Hyper variant. The shurikens are also bigger than the normal and hyper ones.||231|
|Nuclear Bomb||Moderate||The bomb drops even faster, and the dot is nearly invisible. The red dot also beeps once.||297|
|Rocket Noobs||Difficult||Rocket Noobs trade their double rockets for one, large rocket. Rockets have a much larger blast radius. Still wears forcefields.||286|
|Neon Blaster||Very difficult||The laser is fired off much faster, with little to no space left at either corner. Instead of starting on the right to left side, it can start on the left to right side. Either survive by getting to the very corner or get behind the laser while it's sweeping through the map. Another more successful and sometimes more efficient strategy is to reach a high point in the map, and when the laser is fired, jump over it to avoid it.||308|
|Rising Acid||Moderate||Acid is more corrosive, corroded parts deal 28 damage. This causes a decent amount of deaths because people like to run around when a humanoid threat occurs.||264|
|Noobs||Moderate||The Noobs are much faster and deal 42 damage. Jump and speed are both enhanced.||187|
|Pizza Dude||Insanely Difficult||Large pizza boxes are thrown instead, making them much harder to dodge.||286|
|Ninjas||Moderate||Only Shadow Ninjas spawn. They are faster and jump as high as Hyper Noobs, and their ninja stars are thrown much faster. The Shadow Ninja Stars are used, and, thus, deal more damage.||264|
|Caterdriller||Difficult||Caterdriller will dig in a faster attack rate, it will always target a player and it drills back up almost immediately after burrowing.||275|
|Meteors||Very difficult||The meteors spawn at a lower height and fall faster, resulting in less reacting time for players. They also have a bigger blast radius.||275|
|UFO||Difficult||The UFO will move very similar to Hyper, but the laser beam does not stop, and the UFO will constantly target other players with the laser beam still present.||462|
|Lumberjack||Very difficult||The Lumberjack will cut the tree down in 6 quick hits while also the tree being extremely wider. The tree also lands towards a random location of the map, rather than in the middle, at most times.||396|
|Dynamites||Insanely difficult||The dynamites fall faster and explode with an extremely large blast radius, almost as large as Nuclear Bomb’s blast radius. Their fuse time is also shortened.||396|
|Pacman Ghosts (Coming Soon)||Moderate||The ghosts spawn 3x their normal size and move incredibly fast. They also have incredible direction changing speeds which can cause sudden ambushes.||264|
|Sighters (Coming Soon)||Very difficult||Sighters can now attack two players at once while increasing damage over time. The damage per hit caps around 70. It also phases through the leaderboard area next to the shop.||264|
|Crazy Robloxian (Coming Soon)||Easy||The Robloxian is now 3x as fast with a higher pitched voice. Touching any of his body parts will do 25 Dmg.||440|
|Coil Noobs (Coming Soon)||Moderate||They are now Fusion Noobs, wielding Fusion Coils. They deal 42 damage, similar to Noobs. They can even heal 5 HP periodically.||231|
|Flash Flood (Coming Soon)||Moderate||The water now rises to the height of Impossible Rising Acid, and deals damage even more rapidly. The flood also begins to rise right after the announcement goes away, and rises at a faster speed.||253|
|Missile Launcher (Coming Soon)||Difficult||The missile launcher itself is located in mid-air. It shoots faster and can target any player. The missiles also have a larger blast radius.||297|
|Illumina (Coming Soon)||Moderate||The Illumina Man has faster walkspeed and will create a clusterbomb explosion when touched by a player or when the last second ticks. Disaster time is reduced.||297|
|Alien Invasion (Coming Soon)||Moderate||The amount of aliens spawned are increased, they have a wide range, move quicker, and deal 20 damage.||396|
|Tipping Block (Coming Soon)||Difficult||The Block will start moving immediately after the announcement goes away. This time it's 3 times as fast and targets the walls an corners more often.||???|
