Embryo

A very long time ago, aliens planted a few offsprings on Earth’s ocean grounds
until they grow strong. However, humanity wakes them from their sleep with
atomic tests and therefore a big war. The player mans a futuristic fighter
plane to drive them back during 20 missions. While the cockpit perspective
with relatively detailed information prompts and the open locations remind of
simulation games, this is a pure shooter. A radar shows where the main mission
objective is, the player flies there while shooting everything in the way.
Killed enemies sometimes leave power-ups behind which reward additional ammo
or upgrades for the weapon systems. The game tracks locational damage which
may result in malfunction of a ship part.
