A rat or a dog can destroy a vehicle. Hit a dog and the vehicle crashes. Run over one and the vehicle crashes. Larger animals can knock vehicles around; which might be possible in real life but this is not real life. A right or left button tap can cause the vehicles to flip. And anomalies provide a free ride through the sky past clouds and out of the game map. The vehicles need to be fastened to the ground in some way; maybe by that thing that hands down underneath them.
I have been playing and replaying Lost Alpha since it came out including after each patch. It is better than SOC, COP, and CS. I cannot say it is as Good as the Half Life 2, Crysis, Ghost Recon, Battlefield, etc. But I have them and play Lost Alpha because it is more fun even if it needs a doctor ever so often. I am on my sixth or seventh or eighth game with a Far Cry 3 and a Crysis 3 and a Half life 2, and a SOC, and a COP, and a CS in between (I have an play lots of games). LA is like my pet puppy, fun to play with but annoying at times. Great job developers. Keep up the good work.
