if you trust wikipedia:
In his book The Big Show, French ace Pierre Clostermann claims the first Allied combat encounter with a Pfeil in April 1945. Leading a flight of four Hawker Tempests from No. 3 Squadron RAF over northern Germany, he intercepted by chance a lone Do 335 flying at maximum speed at treetop level. Detecting the British aircraft, the German pilot reversed course to evade. In spite of the Tempest's considerable speed, the RAF fighters were not able to catch up or even get into firing position.
there
are other accounts of combat, though sparse and sometimes hard to verify because of the extremely odd nature of the aircraft. Some say odd planes all over Germany were encountered, and the accounts can be attributed to various planes in development, most never seeing "attack" combat roles.
Look at the different planes Germany had "in the works" and prototypes that flew... heck you could make an "argument" that 2/3 of those planes "saw combat" but when the allied aggressor can't readily identify what he is attacking, it is "hearsay"
did the DO-335 shoot down any allied planes? it is somewhat lost in the destroyed records of the war IMHO. there are sporadic accounts of DO-335 pilots killing P-51's but with only the LW pilot account to verify and shoddy at best it can not be conclusive. (with the guns it had any plane "shot down" there were no bail out "survivor" accounts obviously)
I would say the fact it was engaged by a relatively famous pilot that it had combat, maybe for a month. (realistically what are the odds one "famous" pilot who lived encountered the "rarest" LW plane? others
had to encounter it, thought the inability to properly identify it obviously made for some confusion, and ommisions in "official" records)
at least that is my take on the wonderfully beautiful, grandiose, wished for, kick arse, monster cool, spend ALL my perks on, LW ride that
could be in the game
I will say this, of all the "cool arse" possible planes HTC could model, some that were theories, or not developed in time for combat, the DO-335 is a front runner for possible inclusion, as there ARE accounts of it, more than things like say the Gloster Meteor, or other "super planes"
I dare say it would be an awesome 262 hunter in the MA, and really be a fun plane to fly, much more so than the tempest, and it would be a well favored propeller driven "perk plane" in the MA rotation. Come on, who wouldn't want to fly it
