- Cubism - Defend the HQ and the shielding cubes. More cubes are harder to defend, but every cube buffs the bullet capacity and the reload speed. Survive and make sure to not have your HQ hit once! More information below: - How to play Cubism: Advanced tutorial - 1) Protect blue cubes and the very important HQ (different color) 2) Shoot droids/injectors with tap/mouse. There are 4 types of ''turrets''. 3) Red triangles are droids. They infect your defense cubes by hitting them. The droid auto-destructs, the tile dies after 3 seconds. In the meantime, other droids or injectors won't pass. 4) Purple triangle-likes are injectors. These are more dangerous then the droid, because when they hit, the next wave will be harder. Defense cubes will turn purple when hit and die after 5 seconds. 5) Cyan triangles are protective droids. They joined your side. They circle around your base and will slow down until it's about 25% of the original speed. When it hits a droid or injector, it gets destroyed. 6) When lost of protective droids spawn, an very hard wave is coming up due to too many droids/injectors hitting your cubes.
