Bioblade

Bioblade has a fan on the development side: the wiki records it as Nikilis's favorite weapon, and Zyleak's as well. It was the first shop godly released in Season 1, sold as the Bioblade Gamepass at 1,699 Robux. The Bioblade Gamepass page adds that it first cost 2,499 Robux and was cut to 1,699 Robux due to a lack of sales.

Gamepass format

The wiki points out that, like many of the recent gamepasses, this one gave only the knife, with no pet or effect attached. That makes it a clean single-item purchase compared with the bundles that came later.

Look

A large dao-shaped blade, mostly grey, with a lime-green edge and two indents leading into a grey guard that carries three green streaks. A test tube filled to the top with green biotic fluid is attached to the blade, a lime-green circle sits on the guard, and the grey handle is wrapped in tape and ends in a glowing green pommel.

Details worth knowing

It is commonly paired with Biogun, though the wiki does not call them a set. Unlike most weapons, it cannot be salvaged in the crafting station, and it was among the weapons hit by the 2022 duping glitch. It is tier 1, off sale, and available only through trading.
