Siberian Strike: Episode II
The gameplay itself has not been changed. You need to destroy everything on the screen, and your base weapon (two bullets) can be upgraded to up to four. Additional pick-ups include medals for extra points, planes providing extra lives, bombs destroying everything on the screen, and a green icon to summon two companions providing additional fire for a short time. You can also charge a mega ray at will, by keeping a key pressed for three seconds, causing more damage than with regular bullets.
Enemies include tanks, planes, stationary turrets, trains and giant missiles. Certain parts of the environment can also be destroyed to reveal bonuses. The game supports autofire and sports a high score screen.
