Add unlockables each round for kill streaks.
-10 kill streak gives EMP attack, all enemies vehicles lose function for 5 seconds

• 15 kill streak gives air strike on a location of your choice -50 kill streak TACTICAL NUKE INCOMING! Enemy team is dead, your team won the round

Maybe some different actions for different classes but it would help to make people think more before they run into the enemies arms. Also these above is just a suggestion 😅
