Retinitis Pigmentosa

 is a Tier 5 Tank that upgrades from Blocklayer at level 60.

Design
The looks very similar to the Blocklayer, but its main barrel is longer.

Technical
Like the Blocklayer, the 's blocks can go invisible after being still long enough. Despite its appearance, it is not a Producer variant of Blocklayer. Instead, its blocks can become much harder to see than Blocklayer's blocks.

Additionally, they do not need to slow down to become invisible, as they begin to fade immediately after being fired. However, they still benefit from staying still as that is when they become the least visible.

Trivia
