Here's my suggestion, based on the actual circumstances that earned me the Specialist achievement.
Play defense on pl_badwater. Make sure your team has a few competent damage sponges (Heavies, Soldiers, and Demomen) who know how to retreat (you may need to explain that bullets are hazardous to your health).
You want to stay alive. You can facilitate this by always sticking to a buddy. The best buddies to stick to are the ones that hang around sharp corners near narrow corridors:
In these locations, you and your buddy can stay behind cover in the yellow area, and once they are fully healed (to 150%, conditions permitting), they can venture into the red zone for ideal damage exchange along the highlighted lines of sight (where Heavies, Soldiers, and Demomen have a captive audience, so to speak, of the cart's escorts).
Note that the general advice here (be on a good team, play against a bad team, heal everybody) still applies, and that you'll still need classes like Engineers (who can help by putting dispensers near you) to cover your back.
You complete it by getting 200 points in total in Snow Brawl matches.
After you've signed up on a realm, you might want to do a practice round first for the basic controls. They're not very complicated though, and you can jump right into the Snow Brawl event, by clicking the gun icon, selecting the events tab and pressing the FIGHT button below Snow Brawl. Here's a visual guide:
It's your basic third-person shooter. The Snow Brawl game mode is one of CrimeCraft's other game modes, but nobody has any ammo, and everyone has infinite snowball grenades.
However, note that round points do not count towards the achievement — for example, if you get a game mode with control points, holding them will not be your objective for the achievement.
You do get (personal) points for:
- Killing other players (this is where most of your points come from)
- Capping control points, if any
So if there are control points, it is in your best interest to capture them, but then not defend them. After all, the sooner they fall, the sooner you can recapture them.
Anyway, on to the killing. In this game mode, any and all weapons are disabled, but you have a snowball grenade, which is Ability #1 (bound to F1 by default). This is incredibly awkward, so you might want to rebind it to something more accessible, like, say, the F key.
All that remains is to throw said grenades at jerks that are not your color. Some tips:
- Only direct hits from snowball grenades hurt, but they're always an instant kill.
- Trying to sneak up close on unsuspecting or distracted players is probably the easiest way to score a kill. Snowballs are quite slow, so ranged kills are pretty much always luck shots.
- Do not ever stand still. Fidget around. Sprint if you're moving.
- The dodge roll (direction key + Space by default) may not be your bread, but it is certainly your butter. Use it constantly and hope you're up against someone who doesn't know it.
- Unless you're close up, don't let 1-on-1 situations drag on too long. You're about to get snowball'd in the back.
After you've accumulated 200 points in total, the achievement will unlock.

Helpful Preparations
The achievement requires no alarms and no computer. You are allowed to be detected as long as no alarm goes off before in the debriefing screen.
Completion
Part 1: Security Boxes
You're looking for small white boxes on the walls. You'll want to avoid guards and breaking cameras at all costs as there is no way you can take out all of the guards on the level. There are at least 7 guards every time and they seem to be replaced with new ones as you kill them off.
First off, you'll want to check the cameras to see if you can find any of the security boxes. If possible, have a friend sit on the cameras checking for guards that are coming your way at any given time. Check the outside walls and the lobby first, because they are the easiest possible locations for the boxes.
Once you have located a box, you can open it, cut the wire and close it. The guards will notice an open box and call an alarm.
NOTE: You must be standing in order to cut the wire.
This part of the mission is random. There are three security boxes and you need to cut two wires. One of the three boxes triggers the alarm. If an alarm goes off, restart the mission and try again. It can take quite a few attempts to get the correct boxes.
Part 2: Server room
Once you have the wires cut, the alarm for the server room door is disabled. Find the server room. The safest way to find it is to check the cameras for the door. There are four locations where it can be:
Only one should go in and he should have his ECM upgraded to open doors. Sneak to the server room door without being seen and pick the lock when there are no guards nearby. Open the second door with the ECM and grab the server. Guards will notice the second door open and will come check it out. Sneak out as fast as possible and finish the mission.
If you get caught while carrying the server and you have a player with pager-delaying ECMs, have him chain his ECMs one after another as you run out killing all the guards you see on your way. The alarm will not go off until the ECMs run out, but the ECM MUST HAVE PAGER DELAY. If your ECM is not upgraded with that, answer the pager of the guard that caught you and then run and hope for the best.
