There 14 pages on the Markeplace right now. Maybe if you search your favourites ones might find 'em? Plus, there were events where the rewards were avatars (included complete outfits).

I have the same question, I missed the events, it would be cool to have rotations or the possibility to exchange with the community

@King Luiso - I have check it but those are not there. The problem is also that I dont know names of those parts or their set, because they are not listed in user profiles, I can just see them equipped on user avatar.

Look for them in the steam events https://eu.alienwarearena.com/steam/events, they are granted only to those who participate and unlock them through required hours. Doubt that they will be put in the market, it would invalidate the event.

@King Luiso - I already check it, but they are not there. Probably limited stuff which is not available now. Wondering if there is any wiki with all released sets.

@Sebastian_Crenshaw - How did you get that military helmet and vest on your avatar? Why don't I see them in the Marketplace? 😉

@ⓞⓤⓣⓢⓘⓓⓔⓑⓞⓧ - stuff from events - it would not, if you have to buy them fo ARP. I also would have no problem if they would repeat the events to earn them.

@Fruit Punch Samurai - I did just like 3 last events. I didnt know before I could get cosmetic stuff from events.

@ Sebastian_Crenshaw Can we agree to disagree that making them available in the market (even at a very high price) would not encourage participation in events? Some are joining events just for the items. the more unique the more tempting

@ⓞⓤⓣⓢⓘⓓⓔⓑⓞⓧ - there are still arp and fragments as event rewards, so you still need to join because of upgrades
