Hack

Hack is a hacking utility that can be used to steal robots from your opponent and add them to your side. The more robots the opposing team has, the more likely the hack is to work. It's corresponding slot symbol upgrade is "messy hack", increasing the chance to scramble the robot on a failed hack by up to 42%.

Strategy Guide Description
"The first rule of hacking is – if you’re going to use it, don’t rely on it to tip the scales in your direction while you’re taking a pummeling. Picture the scenario; you have no robots on the field and your enemy has a pack of high-level robots. The first thought is “hey, I can just use a hack and snag me one of them fancy robots for myself!” Great idea right? No. It’s not. Here’s why: Is hacking any good then? Oh boy. Here’s the skinny: Well used, it will most probably turn the tide of the entire battle in your favour. However, be sure to only use it when you are safe (in case it fails), or when the potential prize is worth the risk. Stealing a fresh heroic robot is a glorious triumph sometimes just too good to pass up!
 * 1) What if the hacking fails? You’ll get hammered with their full force – Enemy robots would all level up like crazy and your chances to win fly straight out the window.
 * 2) What if the hack succeeds? You’ll get just one unit, which the enemy is most likely going to execute for its’ insubordination in that very same round.

Note: Chances to make a successful hack are listed in the symbol’s description, however you have to multiply the chance with the number of enemy robots. If you roll 1 Hack symbol with only a 12% chance and the enemy has 3 robots, the probability you’ll make a successful hijack is 36%."

How to utilize it and deal with it
If the AI manages to hack your heroic or elite robot, do the following steps:

1. Keep calm and try to not tear your hair out, especially if the AI stole your heroic Droid.

2. Summon firewall and energy leak (for the Drone and Droid) or do laser (for the Tankbot)

2. (alternative) : Shock it. The AI can't repair your (own, hacked) robot.

2. (alternative) : Try to hack it back (only if you have a decent defense)

3: Destroy or retrieve the robot. Then continue battling.
