ZeroVector is an endless retro arcade vertical shoot ‘em up! Blast your way through endless waves of enemy ships seeing how long you can survive and what high score you can achieve. There are four different bosses to encounter, each with their own firing patterns and strategies to beat. Along the way you pick up and use various items like shields, EMP, bomb, and weapon upgrades. Items like shields and EMP can stack so getting two in succession gives the extra powerful deflector and EMP extend. You have a special REVERSAL ability that charges every 20 seconds. Once charged you tap with a second finger onto the screen (or double tap) and all enemy bullets flip around into seeking missiles helping you escape impossible odds and get epic clears. A multiplayer Conquest mode arrives with the 0.2 update and lets you compete against other players in three factions (red, blue, and purple) to capture and control hexagonal sectors on a global map. Achieve the high score on a sector to capture it for your faction and work together to take control of the map. Scores decay over time and sectors can be replayed to defend them and capturing surrounding sectors helps protect them. It’s an all new innovative multidimensional leaderboard system!
