About this game Read the full description
Set in the 90's, sometime after the fall of the USSR, Thunder Tier One is a realistic top-down shooter where you join an elite special operations team tasked with stopping a terrorist organization. In 4-player co-op or solo with AI teammates, players must carefully select their gear and utilize all their tactical skills to complete each operation successfully.

STORY DRIVEN CAMPAIGN



A paramilitary-turned terrorist organization known as SBR have carried out a series of attacks on civilian targets in the Eastern European nation of Salobia. Thunder has been deployed to locate SBR leader Marko Antonov and put an end to his campaign of terror.

Designed to be played in 4-player co-op, the 9-mission campaign takes you through various scenarios where teamwork and communication is key to completing each operation successfully.

In solo mode, you will be joined by three AI teammates who will react intelligently to each situation they face. You can also take charge and issue them with a variety of individual and group commands to ensure they are executing your plan. How much you manage them is completely up to you.

WEAPON & LOADOUT CUSTOMISATION



You decide exactly what you take into each mission, and can choose from a wide variety of weapons and attachments, ammo type (and amount), armor, grenades and tools - you can even choose which camouflage pattern to have on your clothing. The same goes for your AI teammates, you have full control over what they use and carry.

The gear you select will depend on your strategy for the mission. Coordinate with your teammates and go fully suppressed with IR lasers and NVGs for a stealth approach, or go in guns blazing with the heaviest armor and a backpack filled to the brim with extra ammo and frags. Just make sure you have the right tools to get the job done.

REALISTIC GUNPLAY



Thunder Tier One isn't your typical top-down shooter and it's not as simple as staying behind cover and clicking on heads. You need to use both your knowledge and the wealth of weapons at your disposal to be successful.

Each weapon has unique attributes such as handling, rate of fire, muzzle velocity, effective range and accuracy. These characteristics, combined with the type of ammo loaded, will determine how accurate your shots are, how much damage is dealt against armored and unarmored targets, whether the round penetrates an object being used for cover and the damage and trajectory of the round if it does. And ultimately, they’ll determine whether you are able to effectively complete your mission objectives.

ADDITIONAL PVP & PVE MODES



Thunder Tier One has four challenging multiplayer modes to test your skill set.

Exfil: a 4v4 mode where the attacking team is tasked with exfiltrating a package within the time limit and the defending team with preventing it by any means possible.
Advance and Secure: a 4v4 mode where the teams go head-to-head to try and secure a series of sectors and claim victory.
Death Match: the free-for-all classic with up to 8 players.
Domination: a PVE mode where a team of up to four players race against the clock to secure a series of checkpoints, disarm explosives, and defend against counter-attacks.

FULL MODDING SUPPORT



A modding tool with Steam Workshop integration will be available soon after launch, allowing players to add and modify missions, weapons, AI behavior, equipment and everything else in-between.
