How to unlock the Sentry Mode Engaged achievement in STAR WARS Battlefront II - Definitive Guide
TIP: If you are playing against the clone troopers unload your sentry on a LAAT ship (they fire the green laser) for an easy kill. I can get around 6-7 kills in a round from them alone
Sentry gun is a special ability activated by pressing and at the same time. It is a time limited mini gun with very rapid fire.
I recommend an objective playlist like galactic assault where more players will be bunched up.
Once in game select the heavy class, press LB and RB to activate the sentry gun and just kill the AI.
If you are a high enough level you can use the "supercharged sentry" ability card to help but this isn't required.
This trophy is specific to the “Heavy” class and can be done in any online game mode with the exception of Starfighter Assault and Heroes vs. Villains.
The sentry gun is the special ability of the Heavy class so make sure you pick this when you’re starting your game or after you've died. The special ability is triggered by pressing and simultaneously and grants you a sentry gun. The gun is very powerful but takes a while to warm up before firing and it decreases your mobility a lot. The aim here is simple enough, just get a 150 kills with this special ability to obtain the trophy. Try to find choke points in objective based game modes for the most success.
To make things a bit easier on yourself you can obtain or craft a star card called “Mobile Sentry” or “Supercharged Sentry”. Both of these can be very helpful depending on playstyle.
You can partially check your progress towards this trophy in the main menu. Go to the “Career” tab, then choose “Troopers” and find the “Hold the Enemy Back” milestone. Unfortunately, this milestone only will state your sentry kills up until 50, but it’s a good reference as to how fast you’re progressing with this.
EDIT: Alternatively, since one of the later updates this trophy can be obtained in co-op mode by playing with bots which might prove easier than obtaining it in regular PvP games. Credits to Mastodon for confirming this method.
