Four Linux Games I Can't Stop Playing - page 4
The Battle for Wesnoth
Another classic arcade game type is the overhead-scrolling space shooter. Basically you're in a spaceship advancing forward, and you have to both defend yourself from enemy attacks and defeat level bosses. A variety of different armor and weapon enhancements are also offered as you go along. If you've ever owned a game console system or spent any time at an arcade in the late 1980s, you have played one of these kinds of games before.
Chromium BSU is a spectacular modern incarnation of the overhead scrolling shooter. The graphics, sound, and music are outstanding, and the gameplay is challenging but not impossible. There are a few unique elements that I have found in Chromium BSU that most other overhead scrollers don't have. The first is, you can't let any of the enemy ships past you; each one will cost you one extra life. That makes the gameplay much more challenging, but you're also given something else that you don't see in a lot of space shooters: damage leeway. If you can't put enough bullets into a ship to kill it, just run into it and endure a little ship damage. You also don't have to worry too much about dodging enemy fire. Lastly, you have limited ammunition--I have never seen that in this kind of game before.
There is one redeeming element to the game's high level of challenge: the ability to start the game at the last level you completed. So if you get sick of playing after reaching level 2, you can quit the game and come back to it tomorrow and start at level 2. Sure beats feeding quarters to a machine.
