For this strat you do not need a friend to help you out. BUT it will take nearly 3x longer than with a friend!




1) Start a skirmish on a small map. (Chasms is recommend)

2) Chose the Prophet of Regret as your leader.

3) Now chose any UNSC leader because UNSC bases have much less HP than Covenant.

4) Set the game-type to deathmatch and difficulty to easy.

5) Build a temple the moment you enter the match and your fully upgraded Regret will spawn.

6) Send him over to your enemy's base and kill it in like 20 sec.

7) Find his wharthog so the game ends sooner (otherwise you'll have to wait 60 sec for him to default loss for having units but no base).





There you go! Now just 100 more of these skirmishes to go...


(Play some online matches maybe, at least its fun. This is slowwwwww!


Don't understand? Watch this guide. (This strat is slightly slower)

1) Invite your friend to a match. Don't bother to chose the leader or game-type.

2) Have your friend send his scout wharthog toward a rebel base

3) Have your friend self destruct his OWN base. (The option to self destruct a base is in the bottom of the main menu when clicking on the base)

The match will be over as soon as the rebels kill his wharthog and the base is destroyed.

To make things faster tell him to ram the rebels/rebel base with the scout wharthog. Now half of the HP of the wharthog gets melted instantly. This will end the game like 2 sec faster each time... with this strat you save a LOT of time, the solo skirmish strat takes MUCH longer.

And BTW this counts as a win. NOT a forefit. Your friend isn't quitting. He just loses his base and all units in 15-20 sec!

I finished about 20 matches in 10 mins like this and I got the achievement very easily!



Proof this worked for me in 2019:


Enjoy your exceedingly rare Steam achievement!
