Chroma suit looks great! Is that a weapon... oop.
Sounds for thumper are good as well. Will they sound the same no matter the terrain? Is there some thought to how the thumper walks on snowy (e.g. soft snow, crusty snow, hard icy snow) terrain vs. hard rock terrain or terraformed terrain?
I liked the plasma cannon as well, I agree you can't have a game without fire, so any kind of flame throwers or fire weapons are a must eventually.
I mostly played the ranged weapon (charge rifle, sniper rifle), but I really liked many of the others in FF as well. Like the needler. I liked the needler in Tabula Rasa a lot. It really felt like a needler.
As far as assault rifle goes, that seems OK, but I much prefer weapons that make me feel like every shot counts instead of weapons where I fire a bullet stream at a bullet sponge target.
If I am firing a stream of electricity, or plasma, or fire, or poison, then having a continuous stream of that substance which I have to keep on an enemy is fun for me. If I have a gun shooting conventional bullets as a 'stream' then it doesn't feel so fun. It's the same bits and bytes to the computer, but to the VR immersion it just feels nicer to keep a hose of fire or poison on a target instead of bullets.
In that regard, I also really liked in the original Hellgate London that charge/electrical weapon where with the sound and the instant snapping on with the trigger press I really felt like I was wielding pure lightening energy. Does anyone remember that? The Lightening Field on the ground was also excellent as their flame/rocket weapon.
So:
Weapons like FF plasma cannon, big thumbs up. Having to lead the target a bit, big visual and audio effects as rewards for shooting and hitting the mark...
Weapons that stream arcs of electricity, rivers of fire, plasma, poison fluids, Thumbs up.
Ranged weapons like Charge Rifle and FF Sniper Rifle. Thumbs up. Nice to have a big reward when they hit - like exploding heads and dismemberment! Thumbs up.
Bullet streams for bullet sponge targets... thumbs sideways a bit.
