A few notes:
AK is worthless trash; the grenade launcher special isn't worth the drop in damage output compared to uzis.
Polar bears have way too much health and nearly-invisible attacks, but die easily if you sit still and shoot.
A lot of enemies have nearly-invisible attacks - bluish white balls against a bblue background and white snow, with whitish grey snow falling in the foreground. :/ Not a brilliant combination.
Weapon knockback is kind of annoying, especially on the M-16. Also, why even bother with the laser sight? Does it do something besides let you see where you're aiming, exactly like the cursor and the tracer rounds?
Why does accuracy matter if there are no headshots?
Interesting, but derivative of other 1D war games. The different terrains do mix things up a little, but it's impossible to actually destroy the enemy base if the way the American campaign is going is any indication. 2/5
