The game is packed with 40 different levels and 4 levels of difficulty – easy, normal, and hard and an ultra hard level aptly called, Nnnnnnnargh! . Each of the 40 different levels has missions that you need to fulfill. Be prepared to face various enemies who will fire at you until the last member of your squadron dies. So, it is for your own good that you eliminate them first.
The game is also loaded with cool weapons that you can use to destroy your enemies. There are a rifles, hand grenades, sniper rifle, bazookas and even binoculars that you can use to scan the area and find out if there are enemies waiting to ambush you somewhere in the battlefield.
Along the way, as you try to finish the levels, you'll encounter some items and power-ups such as the must-have medical kit, reinforcement sign posts and more.
After you've accomplished a mission, the game either ends it automatically or you need to look for the extraction point. You'll know this point once you see red smokes. Passing through those smokes would signal a helicopter to pick your squadron up.
