Zumbi Blocks 2 Open Alpha
Loot. Kill. Survive. Can you escape ? (probably not) Zumbi Blocks 2 is the official sequel to the 2013 free browser zombie game. Stuck on an island, cut off from the rest of humanity, you wake up. The secret to breaking free from this place lies asleep, underground. From the soil, zumbies emerge.
In short, Steam reviewers most often praise “satisfying zombie shooting” (24 of 99 reviews) and “fun cooperative play” (18); the most common complaint is “relentless fast zombie hordes” (13). What reviewers agree on ↓

“One of the best zombie games I've played for low-end PCs. Despite being an open alpha, it's already incredibly fun and has a lot of potential. I can't wait for the full release!”
— a player, Steam review · 30 hrs played“I wish Steam allowed me to select "Maybe" instead of either "Yes" or "No", because the answer is more complicated. I played during the open alpha, and while I look forward to seeing what changes, tweaks, and additions are yet to come, I struggle to simply say: "Play this game!"…”

I still remember making new friends…”
