looking at this teaser as best i can, looks like lasers suffer slightly from overcorrection, which makes me happy since it means they aren't hyperaccurate surgeon's tools like in older games. that was a worry of mine, since it hampered the utility of every other, slower firing weapon available somewhat.
they also light up like christmas, unlike Autocannon which just flash a moment and cause a nice large explosion on impact, so they're not as useful for surprising people....
