You can keep killing enemies until you get killed if you want a high leaderboard score, but as soon as the boss fight ends you’re done on this map trophy-wise. Then simply repeat the process 3-4 times, and eventually Croc will go down, which will pop the trophy immediately afterwards. From here you just need to mash a lot, and when you see the counter icon, press a couple times. Once it is full, you press and Nightwing will tag-team with Batman to attack Croc. Killer Croc functions much like the big boss enemies you fight throughout the game, where you need to fill up a little bar by attacking enemies. Once you finish the last enemy, the Killer Croc fight will begin and Nightwing will join the fight. Once you reach over 1,050,000 points, enemies will stop spawning, and you can finish them off in any way you want. So it’s very important to not use the takedown move until late into the combo to keep the weak enemies alive as long as possible. When I did my 1.5 million point run, I had a 450+ combo, and I never had enforcers spawn because I kept letting the weak enemies live.

The reason you want to let medics revive enemies is that it won’t advance the spawns of tougher enemies. These pipes will go through every enemy's defences and always hit them, even if they are armoured or have a shield/stun baton. You can also use the Weapon pickup special move ( + ) to pick up pipes that enemies drop.

When enforcers show up, always prioritize them with your takedown, you don’t want to accidentally punch them and end the combo. Use disarm on the guns, or a batarang (tap ) if disarm isn’t ready. They dodge a lot and might make you miss and ruin your combo. When ninjas show up, you can use the special takedown on them. They are the easiest way to lose your combo. When the Stun Baton/Shield enemies show up, use the special disarm move ( + ). Prioritize them and use the Batclaw slam on those enemies ( +, then ). When the medics show up they can electrify enemies. Don’t use the special takedown move ( + ). Use standard punches, counters and dodging occasionally. The way I got the points needed was as follows: Finally, Enforcers and Armoured Enforcers show up. Ninja enemies and gun enemies show up next. Then Riot Shield/Stun Baton enemies show up. Medics and knife/pipe enemies join in next. The way the map works is you fights waves of increasingly difficult enemies, and there is a set amount of each type before it moves to the next tier: You are able to get hit and ruin your combo without affecting the trophy, but since you need a ridiculously high score, it’s in your best interests to not ruin your combo. In order to get that many points, you must try to keep a combo going as long as possible without breaking it or getting hit. The “old adversary” is Killer Croc, and in order to get to his fight, you need 20 Rival points, or 1,050,000 points to get there. This is one of the 2 hardest trophies to unlock.
