Plants vs. Zombies: The Last Hope/Speflunkers

Speflunkers is a special gamemode in PvZ tLH, unlocked in Sandy Sands and develops the theme of exploring the ancient tombs and looting the twisting tunnels.

Background
After unlocking it after beating Sandy Sands - [TBA], Penny notes the path ahead leads away from the tombs they have just battled through, but they have uncovered the longlost tombs of Holediggeria, ancient even by ancient egyptian standards. Even the resident zombies only scratch the surface and upkeep only the most recent of graves. While irrelevant to the main storyline, Penny observes the promise of adventure is tempting and forgotten treasures (and dangers) await them. If the player chooses to enter the tombs, it triggers the Speflunkers adventure

Heroes
In this sense the player plays not as themselves, the generic, invisible gardener, but as a Plant Hero leading a courageous crew of plants into the tombs. There are currently five playable heroes that the player can control, each with a different skillset, strengths and weaknesses.
