Adventure Mode

Adventure Mode is a gamemode playable in Typer Shark (Original) and Typer Shark! Deluxe. The player, playing as the Diver can pick which levels to navigate to, with each level having different enemies. At the end of ever normal level is a Shipwreck, which allows the player to type as many words as possible for bonus points.

This is the only mode where the player can encounter Secret Levels.

Uncharted Waters
"You are in uncharted and deadly waters. Each new level will be more ferocious than the last. How much further can you go?" After fighting through level 12 and defeating the final boss of the game, the Ghost Ship, the player can enter "uncharted waters." From level 13 onwards, the player sails beyond the map and can no longer select different levels, but progresses linearly through randomly generated levels. The difficulty is increasingly ramped up.

Trivia
In the original Typer Shark, the game uses a real world map that places the player in an expanse of the Pacific Ocean, between Tahiti and the Galapagos Islands. In the Deluxe version, this has been changed to a non-descript location with no real-world ties.
