As the title suggests, I've thought of a few weapon concepts that could possibly work well in Destiny's sandbox. I'll try to explain the weapons functionality, place in the sandbox and overall meta, and weaknesses that should be associated with them. 1. Double Barreled Shotgun, Special Weapon -STRENGTHS- Fast fire rate, simultaneous shot functionality, incredible 1 shot potential against high level PvE targets and Guardians in Supers, wider spread for ease of use and possible multikills. -WEAKNESSES- 2 shot limit, very slow reload, low reserve ammunition, no ADS ( LT/L2 fires second barrel), very short effective range, firing both shots is the only way to guarantee a OHK within its effective range. -NOTES- Originally I wanted it to be a Heavy Weapon, but due to the weapons that take up this slot, I felt with the functionality I was looking for it would be underwhelming. I feel this weapon would be very useful for punishing players who miss and/or miss time their shots at close range. I purposely designed the weapon to be a 1 on 1 weapon. Technically, skilled players could get 2 kills with the weapon, but your damage output would be somewhat less than a regular shotguns. 2. SMG, Special or Primary Weapon -STRENGTHS- Fast fire rate, very low recoil, pinpoint accuracy from the hip, next to no accuracy lost will in the air, decent clip size (30+),no damage fall off, decent handling traits. -WEAKNESSES- Realitively low damage, projectile based, moderate reload speed. -NOTES- I wanted the SMG to be a somewhat competitive option over the Handgun class. I chose to make it a projectile weapon so that it keeps the weapon locked to mid range combat. The low damage is meant to counteract the weapons incredible accuracy and ease of use( which are it's primary strengths). This weapon is very much meant to reward players who value mobility and accuracy over damage output. I'm debating whether or not it should be a Special or Primary weapon. On one hand, making it a primary would cause it to directly compete with Auto Rifles and spice up an otherwise stagnant slot. And on the other hand, this weapon could replace Elemental primaries by providing primary like attributes for the special weapon slot. 3. Grenade launcher, Heavy Weapon -STRENGTHS- Wide blast radius, decent fire rate, holding trigger delays blast, Arc trajectory allows for bombarding targets from awkward angles, great anti air and anti camper capabilities. -WEAKNESSES- Horrendous reload, grenades are easily dodged if player opts for spamming shots instead of bursting, misstiming bursts can damage you, low reserve ammo. -NOTES- This is very much a tactical Heavy weapon meant to break up groups of enemies and force your way out of those awkward stalemates that occur when Heavy ammo is in play. Corner campers bane. It might be interesting if we include multiple types of grenade launchers (Timer based, sticky based, wall trap based or good ol bouncing based.) I thought it would be cool to get an Exotic one that takes on the traits of your current equipped grenade ( just the thought of me spamming a half dozen Flashbang grenades into a room makes me all warm and fuzzy inside). These are just a few, and I might edit more in.
