The highest damage ever done in Element td 2 without selling towers. I won't spoil the final wave, but it was surely one hell of a run. Selling towers and using Onyx or Tesla towers would make a much stronger record possible. This should set a benchmark for all future runs to come.

My highest record stood at 303,594,200 for a long time, until i finally aimed to get the highest damage possible. I often ended at wave 63 finishing at around ~300 mil until i found a youtube video of a much stronger build using doom and singularity towers to bunch up enemies to ultimately destroy them with AOE damage.

My goal was 500 mil which i hit a few weeks back. I wouldn't have thought a 1 billion damage run is possible, but here we are! :D
Eventually i found that using Nuclear towers to Heal and damage enemies further increasing the total damage done. My previous record stood at 950 mil at wave 66, but i wasn't happy. After several attempts, i finally survived wave 66 completely annihilating my previous record and finishing with far more than a billion total damage done. A fun journey came to an end with this crazy record hitting wave 67 and finishing with almost 1.5 billion points. I think at least wave 69 is possible with this build, with better Doom tower placements. I can't wait to see whats possible in the future. I think 3 billion damage is possible and im looking forward to see how far you can push this! =)

This run did not sell any towers, but i think if you did, you can push this much further. I think even wave 70+ is possible using that strategy.

This also opens the possibility of suriving for as long as possible. The current record is wave 70 which was done on a different patch. I think wave 71 is possible if you sell towers and use onyx towers.
For now, im very happy to have gotten this run and setting a benchmark for whats possible to achieve. Who knows, maybe 5 or even 10 billion is possible with onyx towers/reselling and better doom tower placement?
