Projectile and explosion changed, and I think it does more damage now.
Samus = op as hell right now
if you get tips up for Samus here's some
-when exiting the boss platform go invisible first. Try to get out before the main force arrives, then circle around behind the bed and attack the people from behind.
-don't be afraid of standing still after decloaking. Since people don't know where you are you pretty much get a free chance to take aim and spam shoot.
-building on the previous tip: if you decloak in a safe place and someone's in the tank turret just spam shoot him to force him to get out or die.
-go for guerilla-style fighting. Kill one or two people and when the main group advances on you go invisible and run away/take a new position
-double jump is really useful with dealing with pyros and straight-shooting units like heavy and sniper.
-unlike the other bosses your dps is based on how fast you click so don't be afraid of missing.
