So far I can only remember the game being that an astronaut has crashlanded onto an alien planet, and starts off with a "light" elemental gun. The astronaut then explores the very large map divided into multiple stages by the "elements" theme, which then unlocks other elemental guns, in no particular order: "freeze", "fire", "missile", and "darkness". Quite notable is that the large map areas are partitioned by doors that look like this:

The curved parts are doors that must be unlocked by shooting it with an appropriately-colored elemental gun.

The story does not seem sci-fi at first, but as the player explores each major area, the player eventually discovers a conspiracy involving a long-lost high-tech ancient civilization, which explains the various unusual-looking enemies in the map. The player then fights bosses at each major area to unlock guns, and finally unlock the final boss.

Can't immediately remember the name (to then find it on Flashpoint). What could this game be?
