Your plan of action decided you make sure your new found grenades are easily accessible before slowly moving into a comfortable prone position. You take your time with your aim, making sure the ground your rest your rifle and your arms is stable and won't shift at the last moment as you take your time to line up the shot. After about thirty seconds you have the gecko closest to the rock ramp up to you in sight, then after one final deep breath to steady your nerves you get to it. You press the trigger, and the rifle booms a deafening noise in the cave and emits a huge flash of light due to the lack of a muzzle break. Your shot is true however, punching right through the first gecko heart and sending it onto it's back where it twitches in place for a bit before promptly dying.
Of course though you no time to really observe that dying, as the other gecko's immediately home in your position due to the muzzle flash of your rifle, they all screech, their lizard ears twitching and extending before they make the dash to get to you, going straight for the ramp. Their a little spaced out, but you hold back for a few moments as you get your first grenade in hand. Two of them will make it to the ramp significantly ahead of the last fourth one, which was still a pretty good scenario if not a perfect one. You press the button and hurl the now beeping explosive toward the other end of the large chamber and to the base of the rock ramp, tossing it ahead of the gecko's to make sure they run into their death, and thankfully thats exactly what they do. There is a clack off metal on stone as your plasma grenade lands right where you want it, the gecko's heading right for it not intelligent enough to understand the danger, a few seconds later they are right by it, and then it explodes. A thunderous bang fills the room as well as a bright green flash that forces you to avert your gaze for a moment. It's followed by a rush of hot wind as super heated gasses disperse, and yet you open your eyes your pleased to see two charred husks that were once geckos, laying still on some red glowing rocks.
But you still have the last gecko to deal with. It's late to avoid the explosion, but seems to have barely stumbled after the grenade went off. You even watch as it runs right through the hot area with care and runs up the ramp! You have about five to eight seconds before it gets to you, but that was enough time to hopefully finish this fight with one shot of your hunting rifle before it could close the distance and engage you in melee.
