So I'm interested in comparing and discussing advantages/disadvantages for some of the weapons in versus. Maybe to better understand and use them. I feel like I'm floundering a little bit with them. So i'll type up what I understand so far. (which is probably wrong) I feel like the hammerburst is basically useless in versus, and the game really comes down to using either Shotgun attacks or the weapons that counter shotguns.
Lancer - Seems to be the "balanced" weapon. Average damage, average spread, average rate of fire. The melee attack is instant kill if it connects, but leaves you vulnerable for a time afterwards and takes a moment to start up when the button is held. Fast reload speed.
Retro Lancer - Powerful shots, slower rate of fire, extremely large recoil/bullet spread. Must be fired with large gaps between shots to maintain any accuracy at range. Fast, damaging melee attack, along with a charge attack that I'm not sure how it works. I seem to bounce off of enemies everytime I charge at them. Reload speed slightly slower than the regular lancer, seems to do well against people charging you for close range/shotgun kills.
Hammerburst - semi-auto weapon with zoom and iron sight capability. Damage is above average but still will take most of a clip at distance, if you're not getting headshots. When being shot while in iron sights mode the view shakes, making aiming difficult. Clip size is below average, and reload time is a little bit slower. No special melee. Seems kind of useless. Few of the maps have any open areas that people get themselves into, and you probably won't get enough shots into an enemy before they can duck behind something at a distance. Using it up close just doesn't make sense because of the slower firing speed.
Shotgun - Shorter range high damage weapon. Fires slowly, can do one shot kills and can be used without aiming at close range effectively. Reload speed is fairly quick. Number of shots needed to kill increases quickly with range.
Sawed off shotgun - Single shot, extremely long reload time. Only works at near melee range. Instant kill at melee range, nearly useless at anything else. No special melee.
I haven't had much experience with the weapons you can pick up but maybe people can discuss the weapons you spawn with to better understand and use them.
Also: everybody playing team deathmatch needs to stop playing this like call of duty. Dying hurts your team. It's annoying to sneak around and be careful, and have two guys on your team with 6 deaths each and end up in a situation where you can't respawn/are outnumbered because some idiot thought he could just run around and use the shotgun.
