If you liked this add on I understand but too many things bugged me for me to want to play this more than once.
The thing that annoys me so much, mostly how weak the thing is in this download. I found that I have to run away from cannons so I can heal and come back and finish the fight. The worst was when you face two at one time making you open to the other one makes it almost impossible to win, all on the easiest setting.
Then the Geth cannon that kills you in one hit was unfair. I was so confused as to what was going on I had to look up a walk-through to figure out what I was doing wrong. There's even a small reference to Frogger where you hop across lava on platforms that sink if you stay on to long.
The on foot sections are cool making you half to think how to advance like destroy a pipe to kill the robots then walk up it to a higher level.
The thing that stopped me from giving this a five is the story which is excellent but as I said the hammerhead ruins this for me. If you really want this I say wait until they bring the price down otherwise just pass.
