I just realized I didn't post the actual translations from my language (I'm just putting in the most interesting ones).
Alien: Svešais ("stranger", as in stranger to life on Earth)
Aliens: Svešie (same but plural)
Alien: Covenant: Svešais: Covenant (we didn't even want to f**king translate it)
Predator: Plēsoņa (direct translation)
The Predator: Plēsoņa: Atjaunots (our language doesn't have the article "the" so it translates into "Predator: Restored" instead)
AvP: Svešais pret Plēsoņu ("Stranger against Predator")
AvPR: Svešais pret Plēsoņu 2 (we're starting to show a pattern here lmao)
