Welcome to Halo 5: Forge, a PC version of Halo 5 that only contains Forge mode and a slimmed down multiplayer. Originally released so you could create higher quality maps quicker using a PC, it gives quite a quick and easy completion but does require playing with up to 8 people.
Minimum system requirements:
I've posted the minimum requirements below but you can try and play the game if you're just short. This may be useful if you want to boost some of the achievements and you have a second device like a laptop. Some maps may struggle to load but simpler ones still should.
Memory: 8 GB
Video Memory: 2 GB
Processor: Intel i5 at 2.3 GHz or AMD FX6120
Graphics: GeForce 650 Ti or AMD R7 260x
Forge mode: The first thing you should do is play the Forge tutorial. This will teach you the basic controls you need to get through the other Forge achievements and also net you the Monitor Bootcamp (70G) achievement.
Thereafter you will want to create a new map and work on getting all the achievements that require creating maps etc. These shouldn't take too long and can all be done on the same map.
Note: Capped (30G) currently requires you to have Halo 5 Guardians installed on your Xbox to gain it.
The next step is multiplayer achievements.
Friendly Forging (40G) requires you to play Forge mode with at least one other person, but the rest require multiplayer matches. For this, having a second computer you can play on is useful. Alternatively, use the achievements boosting thread here to find people.
Most of the achievements require one other player but Running Riot (125G) can be grinded out by yourself.
Take note of Squad Goals (50G) and Playtest (50G) as these require three other people, and finally Community (100G) requires seven other people.
All in all, Halo 5: Forge is a quick completion, and whilst it doesn't make up for the fact there's no proper Halo 5 on PC, if you like Forge or are looking for relatively easy gamerscore from a Halo game, this is it. Just be sure to note that some of the achievements will almost certainly require you to get a party together.
