Season 10 is The Great Flood: an amplified world where the water level has risen. Basket ran this one and built its command blocks, and plays for the Cave Prospectors, the purple team, with pulse2010. The Tab list shows four teams of two: Steel_Douglas and optimus1971 in red, TopStiGear and ty750 in cyan, and OjiiOtousan and erynfaith in orange. A card reads "Episode 01, GopherCraft UHC 10" over the countdown.
A helmet for everyone
The countdown hits "GO!" on a snowy mountainside, and chat fills with Taking Inventory achievements from all eight players. Everybody starts with a clock and a helmet. Basket's tooltip names it: a Diving Helmet with Unbreaking X, Depth Strider III, Respiration III and Aqua Affinity I, marked "Limited Edition GopherCraft UHCX."
Basket gets to work on the land while there is still land to work. A big spruce gives 19 logs, then comes stone for tools and a stone sword. Cows go down for steak, and mushrooms are the backup plan if the food runs out. "No PvP for the first day," a voice reminds everyone.
Out onto the ice
The team heads down to a frozen lake. From the ice Basket can see the spawn structure, the command block build, in the distance. Items act strangely on the way: a sword and some cobblestone vanish and come back. "Either way, whether or not it's a command block, it's definitely a bug," a voice says. The plan is to roll with it this time.
"I guess we're diving now."
No torches under the water
Under the ice it is dark, and Basket has no torches. The helmet has Aqua Affinity, but there's still air to think about, so Basket breaks the leaves of a sunken tree to get a breath. A voice on the team is down to one bubble and has lost a heart, so that player heads back up. Basket finds coal, comes up to make torches, and cooks the meat in a furnace. "I got 12 torches."
The team digs a small stone room off the water with a furnace and a crafting table. "It still is surprisingly very dark," Basket says, even with torches.
Stairs toward the wall
"Dive, dive, dive." The team swims to the lowest point it can find, carves out a room, and splits up to dig in different directions for a better chance of finding something. A lesson from the beta comes up: when you dig a staircase down, aim it toward the wall, "so that if the wall is shrinking, then you have an escape." Iron turns up. Chat stays quiet, and on the Tab list everyone's health looks fine.
A ravine below the flood
Zombie noises point the way to a cave, and Basket comes out at a ravine. Some of its lava is not under water, and a little water trickles in from above. Once that water spreads, mobs might swim up it, so the plan is to keep heads low. Basket goes off to explore the cave. "That's the end of this episode."
The server posts "End of Day 1. Players remaining:" and lists all eight, BasketMC and pulse2010 included. The episode ends with Basket alive underground, then the end credits.
