Gears of War 4

IMPORTANT UPDATE: Sorry, folks. It looks like the recent title update has caused Sniper Strike headshots to no longer count toward the headshot bounty. You'll still get xp for the ribbons and whatnot, but not for the bounty.



This is a modification of a guide originally posed by YAT0, but which he had taken down. It will get you 16K xp for doing just one Wave of Horde, using only the Sniper Strike from the fabricator.

Setup:
1) You’ll need to fire up a second controller and sign in a guest. You can still use this method without a guest signed in, but the game will behave differently for some reason. With a guest signed in the Sniper Strike works more effectively, and I don't know why. I just know that you will more often than not fail to kill all of the enemies with the Sniper Strike when you are playing without a second controller signed in. Also, having a second controller signed in will allow you to earn credits for finishing the wave.
2) Go to a Private Horde match on the map Reclaimed. Set Wave to 49 and difficulty to Insane. The map does not have to be Reclaimed, and based on the comments other people have their favorites. Foundation seems popular (see comments).
3) You’ll be playing as the sniper class. Ideally, your Sniper Strike should be at level 4. This will allow you to maximize the number of ribbons you’ll get during the wave.
4) Set your bounty to Headshot I (7,500 xp for getting 50 headshots). You can craft this bounty for 40 scrap. If you’re at the point where you’re just grinding xp just sell, sell, sell and buy tons of this bounty.

The Grind:
1) Start up the game at Wave 49, then drag the fabricator into the Garage for a little safe cover. Bring your second controller player over to the fabricator also just in case you get downed.
2) As soon as the icon for Sniper Strike is available, fire one off.
3) Continue to fire off Sniper Strikes until the wave is cleared. Wait a few seconds between strikes to make sure that you get the Double, Triple, Quad and Quint ribbons every time. This will affect your xp gain immensely. A good rule of thumb is to fire off the next Sniper Strike as soon as the Quad or Quint ribbon shows up. If your Sniper Strike is level 4 you'll have enough energy in the fabricator to clear the wave.
4) After the wave is cleared and the kills have been tallied, press Start and select Return to Lobby, not Return to Main Menu. This way you won’t have to change any settings and can immediately launch another game on Insane from Wave 49.

You should get roughly 8,500 xp from ribbons and clearing the wave, plus 7,500 for the Headshot I bounty. Ribbon xp will vary based on randomly getting Oscar Mike ribbons. That’s 16,000 xp from doing a single wave of Horde without firing a shot.

UPDATE: Since the other guide was removed here are the xp requirements for each reup (reposted from that other guide):
1 1,069,200
2 1,170,180
3 1,271,160
4 1,372,140
5 1,473,120
6 1,574,100
7 1,675,080
8 1,776,060
9 1,877,040
10 2,079,000

With the new 1-50 class bounties that give XP i would seriously consider doing casual 1-50 over and over for 65k xp (normal + bounty).

UPDATE: Fortifications 2 has been removed from the game. Lovely. So the 1st method is no longer usable.

I have one horde based methods for you, best done with at least 1 partner and doesn't have a net use of any of your resources.

Craft/use a hardcore I bounty. An engineer with turret discount and repair efficient and a scout with health boost and deposit bonus can handle this relatively easily on the fallout map. I would actually recommend starting at wave 11 rather than 1, as you will start with enough cash to build a turret right off the bat. Build turrets on the left wall of the spawn and a barrier across the opening, Suicide on boss waves to get the helicopter. You can spend extra money to build a decoy outside the spawn and a barrier in front of it. Keep enough money to repair the turrets, but spend the rest on decoys out front to level up your fabricator as lvl 2 and 3 turrets will make things go much quicker.

This run will get you at least 25k xp. It will also get you at least 2k xp towards your class, and it will get enough credits for 1.5 horde packs, which will provide just enough scrap to make another hardcore 1 bounty. (Any credits from hitting a 5 level milestone will be gravy).

EDIT 3: - Thanks AGAIN to Piyi Piyi for an amazing video showing how to deal with Guardians and how do the boost considering new updates! Check it at the bottom of this solution...

EDIT 2: - Thanks to Piyi Piyi for some tips considering new classes skills!

EDIT 1: After 2017, february 7th update, headshots made by Sniper Strike hability don't count for Headshot I bounty card anymore. You still can earn a good amount of points without the bounty card (about 8,500 PXP) by playing on the new Inconceivable difficulty.

WHAT IT IS: A boost method using Sniper Strike Level 4 skill. This is the fastest way to boost your Player XP and at least Sniper class at the same time. For the others classes, the best way to level up fast is to play during Double XP Events on Developers Playlist. This playlist becomes avaliable for Season Pass owners and their friends in the lobby everytime a new map is lauched (once a month).

HOW LONG IT TAKES: About 3 minutes, including loadings to start the match and to see the scoreboard.

WHAT YOU RECEIVE: It may have changed after so many updates!!!
> About 8,500 PXP = 170,000 Player XP/hour (Sniper player)
> 720 PXP = 14,400 Player XP/hour (Other player)
> 496 CXP = 9,920 Class XP/hour (Both players)
> 74 Cr = 1,480 Cr/hour (Both players)
> Plus 500 Cr after leveling up 5 Player levels (Both players)

WHAT YOU NEED:
> Two controllers OR one friend
> Sniper Strike Level 4 skill card

HOW TO SET:
> Join a second controller or invite a friend. Don't use guests, make sure it's a silver or gold account, so the progress will be saved, even if it's a dummy account. It will make the process easier and faster.

> Go to HORDE > HOST PRIVATE MATCH, select
Map: FOUNDATION
Difficult: INCONCEIVABLE
Wave: 49
Class: SNIPER for you; anyone except Sniper for your partner.

HOW TO DO:
Go to the Fabricator, pick it up and drop it to make the countdown start. Now take it again and move it to the covered area near you.
If you have a second controller, use it to take the other player to the Fabricator and make a deposit. You have at least 54,500 Energy Points now.

As soon the wave starts, use the Sniper Strike skill. Stay near the Fabricator to receive Energy for your kills. It will grant you enough energy to one more strike at the end of the wave.
Wait 4 seconds (usually it is when The Quint ribbon appears) and use it again and again until the wave is completed. Always wait 4 seconds between strikes, to receive the maximum amount of XP. If you don't, you may waste 5,000 PXP due ribbons not being awarded, because you're keeping the same killchain. When you kill the last enemy, pause the game and hit return to lobby option. Wait at the confirmation screen (YES / NO) until the score board (WAVE 49 COMPLETED) appears. Now you can hit YES and leave. Even if sometimes the game shows 0XP and 0cr, you have received. You can check it at Warzornal and Store.

RESULTS: I guess it's the fastest way to work on the most grindy achievements at same time:

Updated method (by Piyi Piyi)

Original method (by me; rafa1000house)

Ok so this solution will offer a little bit more XP for the sniper strike method by using the Fortifications 1 bounty since the headshot bounty no longer works with the most recent update.

Use the same set up as the other solutions give by going to wave 49 on casual and along with sniper strike, put on 10% build cost. You will be buying barriers as they are the cheapest and with max build cost they will run you 1,800 power a piece. So with having to build 5 for the bounty, that will cost you 9,000 power, leaving you with 44,500 power to spend on sniper strikes. 44,500 will net you 9 sniper strikes in total, with the final sniper strike only requiring you to pick up a couple hundred power after adding in the power you receive per kill (I only needed between 100-200 power to reach the 5k neccessary). Normally you would get 10 sniper strikes without picking up any additional power so you are only losing out on 1 sniper strike, which if would go perfectly would net you 700xp from ribbons for the double-quint and hat trick ribbon. The Fortifications 1 bounty is worth 2k so right there you are +1,300xp every round which puts you making around 8,500 xp instead of the normal 7k-7.5k xp per round.

I realize it isn't much but it is better than nothing at this point. Hopefully with it being such a little amount of difference, the coalition wont put this as a high priority to patch but I am not holding my breath so get after it while you can.

If there is something you think could be better explained or worded please let me know and i will do my best to update the solution. Hope this helps those who still need those last few re-ups (me lol).

Edit: Add A second Controller to gain a few additional ribbons for some extra xp and better spawning of enemies. Thanks to C2DWELL for that addition.

Happy hunting

Video guide that I made for anyone wanting to have a visual.

I have a solution for those who enjoy the grind and are looking for another speedrun.dance

As of today, August 27, 201, the coalition patched War Machine and Foundation. My video below will show you exactly how to speedrun the map blood drive. It takes roughly an hour, it's fairly new so feel free to try it and modify it to make it faster.

What you will need;

2x Scout
2x Engineer
1x Soldier

I found this to be a pretty solid and somewhat quick method to getting 10 re-ups.

Go into a private horde match. Choose whatever map you enjoy most, I personally used Gridlock.

Difficulty: Casual- I increased to normal with stronger skill cards.

Enemy type: Juvie madness

Class: Soldier or Scout, I'd recommend scout as they can take more damage. I used the following skills, health boost, shotgun damage, brawler, rage and health regeneration boost. Its okay if you don't have all these skill cards, the main three to focus on are health boosts, shotgun damage and brawler.

Bounty: You will want to buy the bounty Kills II it's only 40 scrap and nets you 25,000EXP.

The key is to play the first 5 rounds, you will earn the bounty Kills 2 by round 5. Once you have completed round 5 quit to lobby equip bounty kills 2, and rinse and repeat. Starting fresh from a re-up at level 1, the first time doing this will put you from level 1 to level 19/20.

It does become less the higher your level but if you grind for about 2/3 hours you can easily reach around levels 50-60. The only 'difficult' part of this will be the boss wave, some of them can be irritating, I'm looking at you dropshot enemies but if you play on casual it wont be too challenging. Over the past few days I have gained my last few re-ups and got to my tenth re-up.

Any questions or issues put a comment below! Happy hording!
