Honestly, this game gets painful to play at later levels. Take Alien 11, for instance. The enemy have you outnumbered, as well as have better guns, better gun spawns (I always see higher-powered gun types at their spawns), and have A.I.s that , you know, DON'T JUST SIT THERE RIGHT NEXT TO THE FLAG DROP OFF POINT SO THEY CAN BE KILLED WHEN THEY HAVE THE BLEEDING FLAG, unlike your allies. I've tried every tactic in the book beyond different guns, which is hard to do since it takes a while to get new guns.
1. fly a jet through a complicated series of caves.
2. repeat said style of missions approximately 7 times
3. Kill boss before injecting what will actually kill it.
4. spend 2 seconds to fly back to home
5. ?!?!?
6. PROFIT.
Those gas heads are what haunt my nightmares. One of them randomly flew out of nowhere and COMPLETELY destroyed my guy. and crushed all of his bones into paste. I AM SCARED OF THEM.
After running for two thousand feet, the llama finally fell, and while plunging, FINALLY figured out that he was going fast while falling, so he decided to open his eyes. Unfortunately, since speed translates to color, he suffered a epileptic seizure and was unheard of for 14 years after being sent to a medical ward. THE END. otherwise, (Pi+1)/5
