Get Ready for a Thrilling and Innovative Gaming Experience with GROSS
GROSS is a hybrid of tower defense and first-person shooter genres. With its fresh and unique mechanics, you’ll be hooked from the start as you strategize and defend your way to victory.
Defend Your Base in Classic Tower Defense Style
In GROSS, you are tasked with defending your base against waves of enemy attackers. Build barricades and turrets to create mazes, launch attacks, and place traps for added defense. During the construction phase, experiment with different combinations to create the most effective obstacle course for your attackers.
There’s no time limit or wasted resources – you can sell everything you build for a full refund until the next combat phase begins. If you love the strategy of building the ultimate tower defense setup, GROSS is the game for you!
Intense, Fast-Paced Combat
Once you’re done building your defenses, prepare for high-octane action! With a huge arsenal of guns, each with unique ammo types, you’ll need to make split-second decisions to take down waves of zombies. Use full metal jacket rounds to pierce multiple enemies, hollow points to push foes back, incendiary rounds to ignite zombies, or unleash grenades and rockets for massive damage – but watch out, these may also destroy valuable cash pickups.
Additionally, you’ll have access to active abilities for more ways to defeat or distract enemies, move more efficiently, or manage resources. With over a dozen weapons, gunplay in GROSS is always exciting and rewarding. Are you ready to take on the undead?
Money is Key to Success
Gather money from defeated enemies quickly – but beware, others are after it too! Secure it to buy defensive structures and active abilities, and it plays a major role in your score. Every action has consequences; focusing on attackers while your defenses are overwhelmed could turn the tide of battle, but you may lose valuable money needed to improve your defenses.
GROSS keeps you on your toes at all times. Stay sharp and stay ahead of the game to come out on top!
