Koop Atomega PC

Collect, grow, evade and fight as you compete for dominance in Atomega - the fast-paced first-person multiplayer arena shooter with an evolution twist. 

Consume cubes of mass as you race around the arena to grow and grow, through the tiers of evolution itself. Start as the tiny single-celled Atom, and take on increasingly powerful new forms as you aim to reach the godlike majesty of the Omega. 

Battle online with up to seven other players to supercharge your growth, take control of the arena, and power yourself to the top of the leaderboard! 

COLLECT 

Gathering mass is the key to the game – the more you absorb, the more points you earn – and the most points at the end of the match wins the game. Collecting mass helps you evolve into larger and more powerful forms, so the more you collect (or win from other players), the bigger you will grow. 

GROW 

Every character form has its own strengths, and tactical advantages - giving you different gameplay options. Smaller forms allow you to sneak around unseen, while getting bigger will increase your strength and firepower - but make you a larger target. Reaching the most colossal forms will give you the biggest points boost. 

FIGHT 

The setting is the final arena at the end of the universe, and you are battling to dominate it! Dodge, evade, strike and fight as you take on up to seven other players in a series of different arena environments. Collect Power-Ups to temporarily give you game-changing abilities, and Teleport to get yourself out of trouble. 

DOMINATE 

There are many paths to victory in this ultimate David-vs-Goliath battle. Use your knowledge of the arena to outsmart other players, manage your size tactically to avoid attracting too much attention too soon, and gang up together to cut your biggest foes down to size.
