There are only two fights where an ice wall takedown can occur. The first is in the cryo room, where you have activate two switches to clear the room of icy fog. There are two walls on the lowest level which can be used. Get them both here if possible. The second occurrence is during the final Boss fight. There will numerous ice walls and you can do takedowns on Freeze or his allies.
Progress until you are at the Deathstroke Boss battle. If he is defeated and you take damage, either restart or try again later in New Game+ mode. However the battle in New Game+ will not feature counter icons, making it noticeably more difficult. The fight has three phases. In each phase damage him for about two bars of health and he will throw a smoke bomb then leap attack from above. Repeatedly counter it then, hit back. During the first two phases Deathstroke uses a staff. In the third phase he is armed with a sword which offers a quicker attack. There are only three to damage him; counter, strike, or batclaw slam. The best attack pattern is to use counter twice followed by a batclaw slam, then repeating the process. You can also try a strike immediately after a batclaw slam. Do not get too far away from him or he will launch barrels at you. If you get in too close you may not have give yourself enough time to counter.
