Empulse gives me huge Dirty Bomb vibes with the movement and graphics style but it could learn a thing or two from DB.

"Execution" game mode - 6v6, no respawn, best of 12 rounds. no loadout switching during the rounds and short 10s timers between end / begin of next round. (I really like the game movement etc, but i really hate TDM with instant respawn - currently all game modes are basically TDM)

A quick-chat system ala Dirty Bomb would be nice (also called the v-say system. For example: press V for quick chat, press 5 for global, press 4 for "Hi" or 5 for "Bye" in short v54, very easy to remember and use while running and shooting)
In dirty bomb that was used during the rounds for quick communication and it also played some voice lines and just makes the game feel more alive when you have the game characters talk some s*** from time to time :D I guess the difference here is that we dont really have "characters" so all voices would be the same (or maybe there will be cosmetic audio packs in the future?)
