Chromium B.S.U.

Chromium B.S.U. - is a free-to-play arcade game in the shoot em up genre. The player takes on the role of a hero fighting his way through enemy forces. The player's task is, by shooting at enemy ships, not to let them reach the bottom edge of the screen. The player loses one "life" for each enemy ship that reaches the bottom of the screen. In addition to this rule, the game is complicated by the limited amount of ammunition. To win, you have to calculate the number of shots.

In difficult situations, the player has two choices: collide with the enemy ship, causing damage to himself and the enemy, or destroy his own ship - in this case all the enemies disappear from the screen. The first level of the game contains only three types of enemy ships, but on further levels more and more enemies start to appear.
