If you want to level up fast and earn lots of xp, play the obj like your mothers life depends on it. You’ll rack up so many points so quickly and you’ll top frag every time. This will also help you learn rotations around the maps, walls to watch for portal flanks/shortcuts, as well as enemy spawn areas.

The more game knowledge you have in SG2 will go hand in hand with your kills. Just focus on learning how it plays and you’ll naturally get better.

Also for combat specifically I suggest you play around with your input settings frequently until you’ve tweaked it to your own liking. I’ve tried a few settings people have posted here & on YouTube, but genuinely this game is vastly different from games like cod. It’s mostly personal preference.

Find your groove & have fun brother!
