SAS zombie assult two

Some of you may have played SAS Zombie Assault this is the sequence to that game, the game play is the same as the first part with a lot of new functions. If you recollect Zombie Assault One was based in a specific location a map though not too large you had to run about quite a bit.
The new version allows you to unlock new parts of the map, I am not sure if this is a good idea, you need to, to be able to find new guns and weapons.
But the more you unlock the more barricades more the zombies, more killing and definitely more fun. If you have not played the previous version, all you need to know is that you need to kill the zombies and survive.
You are in a room with barricades, the zombies break them and enter, so you need to fix them and kill them to survive. For every zombie you kill you get cash to upgrade weapons and features.
You can also get stronger barricades, sentry guns, etc, or does that make it easy? Not really as the zombies get stronger, variety is the spice of life isn’t it. You can even try Endless Zombie Rampage if you like this game, its quite similar except there’s no safe house like this game, your out in the open.
