About this game
Developed by Sonic Shield and published by Zodiac Interactive, Big Day is an intense pixel-art shooter ARPG. Set in the smashed-up aftermath of a crippling zombie outbreak, you’ll pit your wits (and trigger fingers) against hordes of the marauding undead.
Combining a top-down viewpoint with lightning fast combat, you’ll need to build and strengthen your arsenal of boomsticks to have any hope of rescuing your lost daughter, as well as finding out exactly what started this mess in the first place.
Story:
Zombies! Just like in the movies! Society is on its knees, and simple farmer Pancho must travel across what remains of the planet order to rescue his daughter Liz. Along the way he’ll find himself battling through cities infected by the mysterious zombie virus “Snowdrop”, while at the same time becoming tangled in a shocking international conspiracy.
Game features:
Lightning Fast Combat and Shooting.
Use your array of ranged and close combat attacks to recreate the bloody ballet of movies like “Kill Bill”, reducing the mindless zombie army to glistening red chunks.
Richly Detailed World
Whether you’re slicing flesh on the Manhattan Bridge, or blowing holes in fools while rescuing the Queen in Buckingham Palace, Big Day lets you do it in beautiful pixel-art style!
Explore, Collect, Survive
Acquire a wide range of weapons and items, enhancing and modifying them to give yourself the edge you need to get through the Big Day!

BIG DAY Release Update
https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/31452004/ecc547b0c56f2c750330547e2c395d012b28cdc8.jpg Hi everyone, As you know, we had scheduled the release of BIG DAY for today, 25th September. To meet this launch day, we submitted the release build for Steam review on 19th September. This process normally takes just a few days; however Steam have not yet completed their review. Unfortunately, this means we are unable to release BIG DAY today. The game is in the review process now, and we will update you as soon as possible once we are given the green light to release. Apologies to all those looking forward to blasting zombies today – we know it sucks.Read full article on Community Announcements (Zodiac Interactive)
