Well if we talk about anti-camp weapon, i have suggest. How abot wall-piercing ammo\weapon (for hex-shooting ofc)? I know, make destructible walls it so difficult, but why not make shoot through wall, it is necessary i guess.
I've seen how Hyperboloid's act in TLAmk2.
That becomes a weapon for campers and the side with more wins!
However, a balacned wall pierce weapon might be OK if it doesn't do more than 40 damage and flies slower than the plasma cannon I think.
Oh well, you mentioned "TLAMk2". Because I played a lot on the TLAMk2 and present at the creation of a hyperboloid. The thing is that there is a
player has seen all the enemies through walls, in the end it all came down to shooting through obstacles with hyperboloids. With both sides. I'm talking about something else. For example perk weapons "piercing-walls." For heavy machine guns and other large caliber weapons. Which will sweep into two hexes to the wall with cuts damage by ~25%.
As I see it - if opponents entered the building, then unfold and heavy gunners start firing bursts-hex-attack on the walls, behind which presumably hiding opponents. Thus opponents will not be close standing against a wall. I especially emphasize this point, it is sufficient to
sweep 2 hexes to ward off enemies from the walls. After which it can try to shoot them through the windows \ doors or smoke out flamethrower \ grenades, it will only strengthen the tactical element of combat.
But make special type of weapon for shoot through walls - I think it is
not a very good idea, it would be unbalanced.
