Replacing spawn weapons

When you think about it, it's entirely possible to merge without losing functionality.

primary: laser + shotgun (think HLAC secondary, but weaker)
secondary: melee (shotgun secondary pretty much unchanged)

OR

primary: shotgun + melee (eg. extend some stabbing part as you shoot, making it a bit gunblade-ish, either on shot or an autoattack on a direct contact with an enemy)
secondary: laser (like in minsta or Overkill guns)

OR

primary: laser + melee (melee part as above, laser unchanged)
secondary: shotgun

Option A is my favourite by far.
