HELIX DISCOVERY: The Ball fights differently. It no longer sits in a corner - it circles the DNA core, fast. You still get 10 seconds with your full weapons; then it attacks with the same blackout wave as in the main game and your weapons drop to the basic shot. Hit it 18 times and it lets go of your weapons for good, so you can finish it off with everything you have while it keeps circling. Its circle sits right at the edge of the biggest Venom Field you can build (max level plus every Chromosome), so only a fully grown field can reach it.
HELIX DISCOVERY: The TV has a little less health (650, was 750).
HELIX DISCOVERY: The TV attacks differently. Its screen now shows a question mark instead of one bubble, and the attack is a mixed group: 6 bubbles of random types - any bubble in the game except the Moon - appear all around the edge of the board at the same moment and close in on the DNA core from every side (it used to drop 4 of one type under the TV).
HELIX DISCOVERY: the red button now destroys everything on the board except the boss itself. The Drone's laser shots in the air die with the wipe (they used to fly straight through it), and bonus globes are wiped along with the gems. Red Touch keeps your rewards as before - when its roll wins, the globes stay too.
HELIX DISCOVERY: your weapons now hit a boss's summons and shots, not only bubbles and the boss. The Helix Bolt chain and Venom Arc (Poison Round + Helix Bolt) reach The Spine's mines and golden coins, Prism Lance bounces into mines, coins and laser shots, Gore Round's blast catches them, and the Cryovenom Volley cone swats golden coins. Shooting a mine, a coin or a laser shot also sets off your chain, lance or blast from it, exactly like hitting a bubble.
