Some skills will require more than one action point. You can spend them in one round and they will not be gone in the next round. Always use those points for high value skills when you have some remaining. Unless you are going to win or lose on the current turn, never leave Ability Points unspent. Use leftover points into a bomb, strike or shield ability.
If you have a robot that rolls a low number, you do not have to spend a Re-Spin. Have them change form and get a team bonus. Do the same with all your transformers to turn a low roll into an advantage.
When first starting, the targeting option is unlocked is very important. Use it to eliminate a single robot from your opponent's team. It works well with first strike. Your robots will always attack in order from top left, top right, bottom left and bottom right. Determine the damage each does and decide which enemy is easiest to eliminate. Focus on an enemy robot that you can take out with as few shots as possible and always optimize your strategy to take out the largest amount of hit points.
