Battlefield 2042 (EP)

Hazard zone is a game mode that needs both luck and skill. For every game there are two extractions, all I can do is giving you some tips to help you survive and increase your chance of extraction since it's PvPvE based.
1. You and your team doesn't need to bring any data drive into the extraction heli to count as an extraction.
2. Downing but not out in the extraction heli still counts as an extraction but no drives on you will be recovered.
3. Expect heavy AI presence and 1 to 2 player controlled fireteam at the extraction point(especially E2).
4. Aim for extraction 1 to increase your chances. Don't worry about the lack of drives to extract though, new pods will drop in with 3 drives and orange smoke before E1 most of the time. If you recover them fast with land vehicles you don't even need to get into combat. It's not worth risking it if you are only doing it for the achievement though.
5. If your teammates extracted but you failed it doesn't count. If you extracted and left your teammates behind it does count as successful.
6. Go to pve all-out warfare and kill AI to get the repair system and 30mm cannon upgrade for your LATV4 Recon. The cannon upgrade is simply op in this mode.
7. Always bring a recoiless m5 or c5 explosive(let your teammates bring the scanner) if possible or you gonna have a hard time dealing with hostile vehicles. EMP grenades works well against vehicles(also annoying robot dogs) as well, leaving you a short window to deal all these damage.
8. Your team should call in as many rangers(dogs) as possible while waiting for extract or when expecting heavy player presence. These are very helpful as they not only deal lots of damage but also draw aggro. Most players don't have gadgets to counter these. Note if you get too far from them they will be deactivated.
9. Having both Falck and Angel in your team increases your chance of survival significantly. Irish and Dozer are good choices too.
10. Extraction zones are always wide open areas, stay in cover around the zone until the heli come instead of diving right in, let the smoke and flares of the heli to cover your moves.
11. Recommended weapons are DM7, SVK, PP29, MP9 and LCMG. Sniper rifles are not recommended since there sure to be lots of close combats. (subject to weapon balancing in the future)
12. If you opened cross-platform do expect cheaters.
I think the extraction point on the bridge in Hourglass is the easiest for the achievement. It's very isolated and relatively easy to defend for those who get there first.
Beside all the basic rules these are all I can think of, hope you can make it and make it 25 times. Good luck and good hunting!
Update 21 Dec: You can no longer board the chopper with enemies inside now.
Update 22 June: The devs said Hazard Zone is no longer the emphasis, so you should try grabbing this achievement ASAP before everyone stopped playing. I heard a lot of people having trouble getting into a game. I tried on XSX, it’s really slow to get to 16. However, it is quicker to get matches on Xbox one version (I play in Europe). Last gen console only need 12 players to start a game. When I was trying to stack Xbox one version achievements, getting into a game still requires some patience (about 5-10 min), but it’s still faster than the current gen version from what I’ve experienced. Maybe you could get the achievement there first, get lucky and stack it one more time on XSS/X. In case you don’t know, most achievements are stackable on these two versions by completing certain actions one more time. Make sure you opened cross-platform if you haven’t.
I also found scanners are kinda useless now since data drives are now directly marked.
Update 23 June: LATV4 Recon's 30mm cannon has been removed in Season 5 vehicle balancing update. The Hourglass rework in Season 5 may make my extraction point suggestion obsolete.

I tried to boost this, but we couldn't match all the squads in the same lobby. Your best bet is to get it legit, like I did, with cross-play on and using your microphone. You'll never know the difference until you play with at least one other person who also uses their mic.

For starters: operators. Too often you'll end up with randoms who are either new to the game and/or mode and they pick absolutely useless operators like Boris or Casper. Sometimes they're even "S" level players and still commit to these bullshit-ass operators. Make sure to encourage them to change to something useful. The best squad includes Angel, Irish/Dozer, Falck and Sundance. Angel is a no-brainer, you get an almost continuous flow of ammo, with the ability to restock on ammo for the Recoilless M5 being the biggest upside of Angel. Whoever's playing as him should call in a resupply crate after engagements in which you used a lot of Recoilless ammo. It goes without saying since I mentioned the weapon, that two of the four players should bring a Recoilless M5 with them. Moving on, Irish/Dozer are generally useful, as HZ wasn't designed with a lot of care and you can get shot from basically every angle, almost at any point of any map, especially from PC no-lifers. If you make it to the Osprey, their role is to use their shields to protect the other three players behind them while inside the aircraft. Falck is also a no-brainer, keeps everybody healthy, but if it's one of those days where you can't seem to be able to do a lot of healing and you or your teammates keep dying, consider Paik, as she 3D spots whoever does damage to her. Finally Sundance is super dangerous and in the hands of a good player they can do a lot of damage to infantry and vehicles, plus her ability to essentially fly is almost game-breaking.

Loadouts:They wouldn't give everybody the factory M5A3 if it completely sucked, so I recommend sticking with that until you get enough Credits to keep bringing your own M5A3, modded with attachements that increase accuracy when moving, as moving will keep you out of danger. The G57 is fine, just make sure you customize it beforehand so it shows up with the attachments you want in the HZ menu. Two of the four players will take a Recoilless M5, the rest can benefit from the armor plates, just remember to put a new one in once the first one breaks. As for throwables, split things again and have two players carry smokes, most likely Falck and Angel so they can revive and resupply with more safety and the other two frags or incendiaries. The latter are particularly useful if another squad beats you to the inside of the Osprey. Finally, as far as Tactical Items are concerned, grab as many Redeploy Uplinks as you can. If you can start with four, you'll have that many more chances of avoiding a wipe.

General strategies: As I said before, you can get into trouble in a matter of a few tenths of a second, due to the design (or lack there of) of the mode and the skill (or cheating level) of the enemy players. Once you drop in, locate the nearest Data Drive drop and go there. Be mindful of where that's located so you know the directions from which enemies might come from. Since this achievement takes longer than the one for extracting with 50 drives, don't worry about hoarding drives. Worry about successful runs. There are only two opportunities to extract and those are revealed four minutes before the aircraft leaves. Therefore, be ready to move accordingly. If you pause and go to "Players and Squads" during the lobby phase, you can tell how many squads are dangerous by looking at their level and other details. If you see for example a squad of four PC players with Russian names and high levels, you'll know they're probably top players and maybe it's better to let them extract (or get wiped trying) on E1. Granted, you'll get more resistance on E2, but I found out that most of the time there are one or two squads of top dogs and the rest are ordinary players like you and me.

Use the call-ins. If you find a Ranger, call it in immediately, unless you got an LATV rolling. If you find an LATV uplink, make sure whoever has it fully upgraded calls it in immediately. The 30mm (yes, not the 50mm one) gun and the self-repair upgrades are super, duper important. The only instance where you should wait is if you've found yourself on top of a skyscrapper. Wait to see where the next extraction is and then parachute down and call it in.

Keep moving with it, the same way you should keep moving if you're on foot. Many times you get tunnel-vision on a group of enemies far away or near enough but at a much better position that your current one. Just retreat and let them think they won. Retreating is also crucial if you are the only one left and you don't have a Second Chance redeploy because you've either used it already or because the E1 extraction has passed. Run to a safe area and use the Redeploy uplink. I once won a round and extracted with 12+ drives because my squad had used eight (8) redeploys and the others simply couldn't keep up with us coming back again and again.
