Controls in the game are made easy with simple swipe gestures - very much similar to the game, Marvel: Contest of Champions. Refer to the images below to easily recall these gestures when playing the game.
Right Tap: Light attack or Shoot when far away
Right Swipe: Medium attack or Dash forward when far away
Right Hold: Heavy attack - Transform into alt mode and break through blocks
Left Swipe: Dodge
Left Hold: Block - reduce incoming damage
Swipe Up/Down: Sidestep up/down
With these simple controls, you get to produce attack patterns from which you get to develop effective combos. A number of successfully hitting combos can add up to your total earned experience points (XPs) every after match.
Here is a good example of a good combo:
1. Make sure you have your special attack gauge full (or almost full) and dash far away from your opponent
2. Try to shoot from far away and successfully hit the enemy with at least two shots (the more the better).
3. After successfully landing at least two shots, quickly dash forward to the enemy.
4. Put up a great combo like light, light, light, and heavy attack.
5. If luck would have it, try the light, light, light, and heavy combo on more time, else skip this step.
6. Finish up with our special attack.
Take note that attacks/defenses work on an RPS like mechanic. Each one has its pros and cons. Light attack for instance have quick successions which gives them a high percentage of consecutive successful lands. The drawback is that they happen to give-off just a scratch to the enemy. Medium attack is slightly slower, and the heavy attack is produced with quite an animation which is easily countered. However, the Heavy Attack can easily break a good crouch/block from the enemy. Also make sure that the enemy isn't blocking whenever performing a Special Attack in order to successfully land a big hit.
In addition to this, refer to the class guide in this game guide (see Table of Contents at the right of this page) to see how your fighter's class affects its effectivity on the matches when paired up with other Classes. Other than that, try different attack patterns and combinations as you progress in the game. During the first few chapters, continuous attacks would suffice as long as you have a strong bot to fight for you. Later in the game though, you'd be surprised to how far challenging the opponents become. Suddenly, class selection becomes all too important as well as dodging and blocking. Nonetheless, you may also choose to repeat/replay chapters to farm for Resources to upgrade your roster of fighters.
