The game will follow the same plot as the original. THQ Nordic's announcement featured the following overview: "Are you ready, kids? The cult classic is back, faithfully remade in spongetastic splendor! Play as SpongeBob, Patrick, and Sandy and show the evil Plankton that crime pays even less than Mr. Krabs. Want to save Bikini Bottom from lots of rampant robots? Of course, you do! Want to underpants bungee jump? Why wouldn’t you! Want to join forces in a brand new multiplayer mode? The battle is on!"
There have been online petitions from fans wanting a Battle for Bikini Bottom remake as far back as 2014. According to Gematsu, the game will be "faithfully remade in spongetastic splendor."
THQ Nordic created a Flash-animated teaser trailer to announce the game. In it, SpongeBob wears his helmet from the original Battle for Bikini Bottom and even does the original pose from the box art. The trailer was released alongside a piece of concept artwork, showing shaded artwork of the playable characters: SpongeBob on top of a defeated robot, Patrick eating a throw fruit, and Sandy swinging on her lasso.
Rehydrated will also feature cut content from the original, including a cut boss fight with Robo-Squidward.
(NOTE: This remake is currently in development, so anything listed here is based on the footage shown at Gamescom 2019, and may change over time.)
The graphics and visuals have been improved, making the game look a lot more realistic.
Many of the tikis and robots have received redesigns.
When you get close to a robot, their eyes will turn red as they chase you.
When fighting King Jellyfish, the "Mini-boss" theme plays, instead of the regular "Jellyfish Fields" music.
There is only one confirmed obtainable spatula in the game so far, which is "Top of the Hill."
The "Cowa-Bungee!" golden spatula is unobtainable, with the bungee hook being removed, and a sign in front of it saying, "Coming Soon!"
Hans, who is supposed to take the player away whenever they go out of bounds, is not present in this version.
During the Jellyfish Fields level, it was daytime in the original but in the remake, it is sunset.
Characters now move and emote more during conversation scenes, and their mouths are fully articulate instead of just flapping up and down.
Before a cutscene or major conversation scene starts, the scene goes to black and fades up on the first character who speaks.
A sound effect plays when advancing through the text box.
Just like the original game, this remake game will be released on the PC.
This game is the first for many things.
This will be the first SpongeBob SquarePants video game to be released through Steam.
This is the first SpongeBob game to use Unreal Engine 4 as the game engine.
Unlike the original game, this remake game is confirmed to have an ESRB rating of Everyone 10 and Up. This marks the second SpongeBob game that has an ESRB rating of E10+. The first is Plankton's Robotic Revenge from 2013.
While the original game is well-known for containing many references to the show, this remake game is going to make references to newer episodes. The original game only makes references to the pre-movie episodes (Seasons 1-3) due to what was out at the time in 2003. Purple Lamp Studios felt it was necessary to add a little bit extra for the fans. So this remake is going to have some references to episodes that came out after season 3.
Purple Lamp Studios noted that the original game was based on SpongeBob's season 2 design for his 3D model. In this remake game, SpongeBob's 3D model is based on his season 12 design. The developers have stated that the 3D model change was due to how SpongeBob’s shape and color have changed slightly between season 2 and 10 seasons later in season 12.
Unlike previous PC versions of SpongeBob console video games, which are made by AWE Games, this game marks the first time that a SpongeBob game on PC will be the same as the console versions.
On the box art, SpongeBob does the same pose as in the original box art except he does not wear his army helmet and his left eye is enlarged.
Patrick is shown eating a throw fruit on the cover.
On the PS4 and Xbox One covers, the Krusty Krab can be seen in front of the lighthouse, but SpongeBot SteelPants is missing from the background. On the Nintendo Switch cover, SpongeBot SteelPants can be seen in the background while the Krusty Krab is missing from the shot. The PC cover is somewhere inbetween, so it is able to fit both the Krusty Krab and SpongeBot SteelPants. This is due to the size of the game cases, as the PS4 and Xbox One cases are wider, the Nintendo Switch case is taller, and the PC case is just about in the middle.
