The first mission

The kill-team progressed rapidly deeper into the tunnels. The overwhelming silence after the battle reverberate your armored steps like a storm. You arrive first at a similar room as the one you fought in, it was evidently were your foes were packed.

You take another tunnel going down. Stein indicate that those don't seem traveled, as there is very limited signs of trafic in or out of the room. Except for the movement that you caused of coure. You navigate more sinuous tunnels at a brisk space. The deeper you go, the more you notice small holes in the rocks until they are almost everywhere. Stein point out furrow-like markings on the ground. Eventually, you notice some larva looking xenos slithering down the tunnel, a few others drops from the ceiling or the walls. They seem to be able to eat their way through rock formation with ease and be heading in the same direction that you are.

The team stop at simultaneous signs from Stein and Ar'Mat. About a 100 metre deeper, the tunnel widen. You can hear the presence of massed creature. They are quiet, but it is impossible for such a great many creatures packed together to be totally quiet.
What do you do?

You arrive at the bottom of the tunnel and a vast chamber open up before you. An horrifying tower of chitin and tentacles stand in the center in a pool of acid. Its appendages reach the floor, ceiling and walls in a moving web of flesh. Around it is a swarm of Termagaunt that let out strident screams as they raise their gun-like arms in your direction.What do you do?

The room ahead gave the Salamander Librarian pause. His sense of the Warp forewarned him of what was to come and he shared this information quickly.
"I sense another of the larger creatures that guide the horde brothers. This one is significantly stronger then the last. Seek it out and destroy it with priority."

"How about we throw them a few grenades before engaging them..."

Cloten says, "We all have grenades, perhaps a volley to soften them before we go for the throat?"

Though there was no juicier target for grenades, Petrix counted on them wanting to close the distance and swarm them. At this range, and perhaps a little closer, their armor and firepower would scythe them down. Most concerned with thinning the herd before reinforcements arrived, especially whatever psychic monstrosity Ar'mat had detected, he knelt in the open at the entrance to the cave, laying down a shower of flak from his bolter's Metal Storm magazine. He didn't issue orders, confident that his squad would take up positions and bring their wrath on the enemy without hesitation...

Cloten, attuned to the squads movements and Petrix' leadership, snaps a frag grenade free and flings it into the front rank of the Termagaunt gunners. Then runs to the Stalactitite s5.Half action: standard attack
Half action: move 5m

Standing steady, Kenshen survey the range and assimilated an understanding of the landscape and positions. Brother Petrix starting them off, the rattling and multi-pitched grinding of explosions. The eruptions of yet another battle between the Truth and Light of the Emperor and the grim darkness of the encroaching void.

Stepping forward, Ar'Mat braced himself against the roused horde. He raised his blessed flamer and awaited the coming of the horde before squeezing the trigger. His armor reflected the pouring flame as chitin disintegrated and flesh melted. Still, the horde gave him great pause. He did not waver, but there was concern to him. Could he and his brothers best this vast horde?

The psychic pressure from the center was strong, making it hard to focus. The Kill-team could still, but barely, stay in sync. Cohesion 5->1

Brother Petrix opened the fight with a volley of Metal Storm bolts into the swarm. Termagaunt hordes M69->M62Brother Cloten grenade lands in the middle of the horde for great effect and he takes position with one quick jump behind the second stalactite (S8) . Termagaunt M62->M57

Kenshen heavy bolter wreck devastation in the first line of the Tyrannid. Termagaunt M57-M48Ar'Mat stand his ground and ready his flamerBrother Elyas fire his bolter at the horde. Termagaunt M48->M45

Brother Stein also throw a grenade and jump forward to a stalactite (S5). Termagaunt M45->M40

The Termagants keep their front line full with by moving those who were in the other side of the room and fire back sending a rain razor-fanged borer beetles in your direction. Most of those ricochets harmlessly on armour and rocks, but a nasty shot hits Cloten's leg for 8 wounds.The vine-like appendage start moving in your direction, some try to grab Stein and Cloten who moved forward and more are extending toward the rest of the team. It gets a grip on Stein. It is your turn to act!

Ar'Mat's flamer barks at the vines as they reach for his battle-brothers. He then advanced stoically to engage the thing, joining Brother Cloten at his stalactite. He wondered briefly if it was sentient and perhaps was the creature causing the overwhelming psychic force. It might even be what directed the horde. But there was no telling how tough it was. Perhaps dealing with the swarm first was more prudent. It was up to the squad leader to decide.
"Brothers, destroying the pillar may disrupt the Tyranids."

Cloten snarls at the sudden pain, but feels his holy armor seal. He grabs the heavy flamer with both hands and waiting for a break in the storm of shrapnel from their weaponry, steps around and unloads the heavy flamer at the front ranks, centering on the tendrils reaching for him.

Missing his parry, Stein starts hacking at the vine to get rid of it...
...but only his first attack connects on the vine...
