Way to unlock the mission: You get the opportunity to start this mission while exploring freely The Bowery district.
The beginning of the mission
While exploring the central part of The Bowery you should hear a baby crying. Make it over to the lowest level (under the glass dome) and locate the pram shown in the screenshot. A close examination will reveal that it is a trap set by Shiva. Press the counter-attack key/button at the right moment to receive an invitation to participate in the first test.
Shiva's first test
The "innocent" policeman captured by Shiva is being held in the South-Eastern corner of the Coventry district, where it borders with the Diamond District and the Burnley district. After you get there, you should hear the cry coming from the policeman and you need to locate the door to the Shopping Complex.
Of course, you should not attempt to cut off the cop straight away, because he would die electrocuted. Instead, use the hook to make it over to the ledge on the right, and locate the hole that Batman will be able to squeeze through. After he does, destroy the first generator.
Get prepared because there will appear three female warriors, sent by Shiva, right after you disable the generator. During the fights, try to react properly to their attacks, first of all, by pressing (the blue symbols) or holding down (the yellow symbols) the counter-attack key/button. You also should not worry too much if the warrior that you are currently attacking disappears from your sight for a moment. Simply change targets in such a situation. Continue fighting until you have defeated all of the warriors.
Now you need to reach the generator on the left and you need to start by selecting from the inventory the grapple. Use it to extend the rope, grab onto it and reach the balcony to the left of the hostage policeman. Just like earlier, you need to destroy the generator.
Just like in the previous part of this mission, there will be three female warriors for you to defeat and winning should not be too difficult. After you have secured the area, extend the rope again with the grapple and return to the main area. Use the batarang to free the policeman. Talk to him to learn about another law enforcer.
Find the second policeman
Turn on the evidence scanner and examine rim of the fountain that used to be connected to the generators, to find a trace of blood that can be scanned. Leave the detective vision on, return to the Coventry district and follow the traces on the ground.
Along your way to find the second policeman, you should not encounter any enemies, but you will have to climb onto several ledges above. After you reach your destination, the policeman will turn out to be dead, unfortunately. Examine his corpse and be prepared for Shiva's another attack (the counter-attack key/button).
Reach Shiva's staying place
Shiva's hideout is in the lobby o the Wonder Tower in the Sheldon Park district. Approach the tower from the South and note the snipers occupying some of the building's corner balconies. Depending on which you prefer, you can either try sneaking past the snipers, or take them down by surprise. Regardless of which you chose, enter the Wonder Tower - Lobby.
Defeat Shiva and her goons
Start the fight with Shiva by pressing the counter-attack key/button to repel the simultaneous attack from all of the Batman's enemies. In the first part of the fight, Shiva will be helped by the female warriors that you have already dealt with in the mall. As a result, you should know already how to react to their attacks.
To the extent possible, focus on inflicting damage to Shiva, because she will have to lose enough health points for the next phase of the fight to start, instead of eliminating all of her warriors. Also in this case, the key to success is flawless countering the attacks although you do not need to restrict yourself to defensive actions and you can also search for opportunities to deal damage.
After Shiva loses around a half of her health bar, the second phase of the fights will start. This time, Shiva will summon martial artists. In case you have forgotten, you need to keep in mind that they are able of countering some of Batman's attacks. As far as countering is concerned, you need to remember to tap the counter-attack key/button twice to counter the entire sequence.
Also in this phase, you do not need to eliminate all of the Shiva's men, although this can be helpful a bit, while attempting to attack the boss. The Assassin will probably start using the katana so, do not forget about the necessity to hold down the counter-attack key/button. Keep depleting Shiva's health bar and be prepared to tap twice the key/button shown on the screen, towards the end of the fight. This will block the last blow with the sword. This is the end of this mission.
