We can change the resolution up to 1024x768 and enable 3D acceleration (however it runs sluggish [!] on modern hardware, better go for software mode)
The movement of the ship suffers from some inertia (in all directions) so, sometimes the ship can go underwater.
The player's machine has two flying modes, aircraft like and hovercraft. (in the picture, aircraft mode)
After some scouting, we find the first "easy" bugs. When the aim sight is over them it turns red. Fire!
This is the first level's hive. Its usually protected by three creatures. Only after their death the player is allowed to destroy the hive.
After destroying the creatures and their hive the world is safe, so we go down the hole to the second world.
In the second level the player must prevent the creatures from kidnapping the people (within the given time).
