Sprocketon

I was on an alien planet planet that had recently been teraformed by humans. My team and I had been sent to investigate the disappearance of all the colonists. (haha been a while since I played Mass Effect 2) The planet was a lot like Earth except the grass had patches of blue and the sky patches of green. My team, a big bald guy, a short skinny one, and a women with short black hair, split up to find clues. I came upon a large storage unit that had been changed into a nesting ground filled with aliens in green, slimy cocoons. They looked like knee high versions of the aliens from AvP. I snuck around carefully while searching for survivors and found a small group that had been incapacitated and awoke suddenly as I arrived. I was escorting them to the drop ship when the alarm for the storage unit went off and woke up all the sleeping aliens. The alarms were strange lumo boxes that began to glow in many colours that had sirens like a fire truck. I told the small group of survivors to run to the launch pad while I gathered my team to leave. I took the stairs on to one of the metal, cube shape 'buildings' and saw the women and the big dude fighting off a group of beasts, the short one was now fighting alongside the aliens. I figured he was the one who betrayed us and set off the alarm. I had never been so furious in a dream before. I threw a grenade that gave off a high pitched tone to try to draw them away long enough for everyone to make it to the launch pad. I then made my way there myself but as i got closer they took off without me. This didn't phase me much because I felt like the mission was a success and the survivors safe, so I took shelter in the storage unit and waited for the final battle but there was nothing... just a large empty room and silence. everything, me included became completely still as I began to wake up.
