In October 2013, a Korean game development company called Clegames Inc. published its first middle-core game called Soul Seeker. Clegames Inc plans to be a global middle-core game developer and is also building Zombie Hunter D-Day, one of its other game releases. ZOMBIE HUNTER D-DAY is downloadable for free from the App Store and Google Play. It's a single-player game, but you can install it on tablets and smartphones that run on the Android or iOS operating system. The game offers smooth, realistic graphics in 3D. Players can battle zombies in many different environments, including forested areas with high trees and skyscraper cities. In addition to that, they can fight the undead in structures such as homes and stores. You can change the game's graphical quality from low to high, or medium. High quality will help you see the game better. Consider lowering the quality of the game’s images when switching to a lower image quality. This will reduce battery life more. Additionally, the game’s sound is so vivid that it drains battery quickly. During battles in Zombie Hunter D-Day, you can hear the sound of guns and the roar of zombies. Additionally, the game features dramatic background music that can be turned up or down as desired. This is so that gunfire and other sounds don't disturb others when played in public spaces.

The zombie virus transformed everyone into a mindless, shuffling hunger victim. The virus-infected are now hunting down anyone remaining in the world to devour. They found your remote hideaway and are currently searching it. The rescue team must survive 80 days until they arrive. This is because you are the only one who can survive no longer in this closed in place. Keep fighting off the zombies and find a way out to move onward. In order to perform the task, you need to use weapons to fight and destroy all zombies. Zombie Hunter D-Day gives players primarily use guns to fight. To use them, simply touch the screen on the appropriate area. During battles, you can use two different weapons. You can change between them by tapping the exchange icon next to your currently equipped weapon. Likewise, you can swipe the left side of the screen to target specific targets. Up to three grenades can be used in each battle. Additional grenades can be purchased if additional slots are unlocked. Grenades can be used to create an explosion that damages all zombies, as well as to regain health when near a health station. A fast way to earn bonus points is to target specific areas of a zombie's body— like the chest or head — that present weaknesses. Exploit the zombie's vulnerabilities to dispense with all adversaries with ease. The game features an expansive collection of firearms. The popular Thumper and Blaster guns are in addition to the more rare AKS-74U, Blaster, Striker, Moe Carbine, Raging Bull, Mossberg and Plasma-L. Each weapon has four indicators which determine its power, rate of fire, critical rate and reload amount. Additionally, many of these weapons have high power indicators next to their names. This extremely expensive gun allows you to obliterate a large number of zombies. However, you need money to buy it before it becomes accessible to you. You can earn access to it by fulfilling a certain requirement prior to acquiring it. In order to unlock Moe Carbine, you need to have 3 or more max upgrade weapons. Similarly, you need to upgrade to Level 5 of 5 skills — which requires upgrading your guns — in order to unlock Raging Bull. Finally, the game allows players to strengthen their weapons by upgrading them. Investing in the best weapon or upgrading your current firearm saves time. This allows you to quickly complete a project. The protagonist in Zombie Hunter D-Day has five special skills. These include the ability to headshot (increase Weapon Power), increase HP, increase CRIT (for increased damage against armored targets) and enhance the power of grenades (which increases the number of grenades thrown). Once these skills are upgraded, the protagonist can defeat more zombies faster. The game offers various options for fighting against its enemies, such as Painkillers, Bonus EXP and Quick Reload. Additionally, the game features Painkillers for easier going through battles with different types of zombies and giant boss zombies. Purchasing these items doesn't automatically grant access to them; instead, you need to specifically purchase each one. Each item also has a specific purpose that complies with its name. For example, purchasing painkillers blocks zombies' attacks automatically.

Hosting 4 distinct settings, the publisher’s Zombie Hunter D-Day employs a first-person perspective. Zombie Stage Mode allows players to clear a stage by destroying all the enemies in that area. Once a stage is completed, the number of zombies it contains will increase gradually. This leads to dramatic battles as the increased zombie count. The second mode, Zombie Defense Mode, requires players to defend against increasing zombie waves. Special weapons in Zombie Defense mode can destroy large groups of zombies at once. This mode also gives players the ability to collect coins and gold. In the third mode, Boss Raid Mode, you fight a powerful boss zombie with help from a drone. You can earn coins and rewards after defeating the boss. Unlocking Bonus Mode is the last action you can perform. When you unlock Bonus Mode, you can only play in this mode. Clearing 5 stages grants access to the Bonus Mode, which can be played once per completed run. By exploring all available modes, players can discover many intriguing facts and anecdotes.

There are up to 15 languages featured in Zombie Hunter D-Day, including English, Simplified Chinese, Traditional Chinese, French, Portuguese, Spanish, German, Bahasa Indonesia, Italian, Russian, Thai, Turkish, Vietnamese and Korean. This allows many players around the world to complete the missions faster since it features so many additional languages. Playing Zombie Hunter D-Day doesn't require connecting to the Internet. It doesn't matter which language you choose in the game's Settings; changing languages is that easy. Exploring the available options is highly recommended; there are many appealing things to discover.

Zombie Hunter D-Day makes use of a unique blend of unique and eerie design elements. Many of its furnishings don't have a high demand for luxury.
