Players who aren't wielding weapons will be able to move faster, potentially evading combat situations. Entering this "Exploration Mode" in combat can also impart some benefits, namely that enhanced speed couples with shield regeneration. That speed could allow a player to minimize the damage inflicted upon them by attacks but also leaves them open to greater risk of harm, should they take a direct hit. The tradeoff for that speed is lowered damage resistance. Earthrise will offer certain abilities that affect battlefield movement as well. Have a look at "The Beauty of Speed" for more on Earthrise's combat system, and the related discussion taking place among the game's community members.
