It has no purpose in the game other than to hint the Megalodon's presence in the game. It gives you a hint that there are sharks that are to be unlocked even after the Great White Shark, since upon initially unlocking the Megalodon Relic the Great White Shark appears to be the final shark in the game, though this is not the case.
When you unlock the Great White Shark and play it once, the Relic of Megalodon is replaced with the Megalodon itself. This makes the Megalodon available for purchase. The Relic of Megalodon is one of four relics, the others being the Relic of Big Daddy, the Relic of Mr. Snappy and The Relic of Alan.
- The Relic of Megalodon is a unique item. It serves absolutely no purpose other than to suggest that Megalodon is the shark after the Great White; it cannot be equipped, cannot be found in the map and has no quantitative benefits.
- It is similar to The Relic of Big Daddy, The Relic of Mr. Snappy and The Relic of Alan.
