And I am done. Omega Syndrome is beaten.
It was quite hard in the end. The enemy squads in the final location were tough... I'm almost sure it's impossible to beat it on Ironman, the RNG simply fucked me too many times. Wearing best armor and having 68 hps was no protection against smgs dealing 50-200 damage with a single burst. Finally, most of those hard battles were avoidable (many paths you can take), and the ones that were not - I soldiered through thanks to savescumming. There was simply no other way. Fighting in narrow corridors, were you have nowhere to hide from enemy fire was not a matter of tactics, but of attrition and sheer luck.
Anyway, despite the high difficulty curve, the game was quite short. The campaign took me about 15 hours, I reached level 8 (which is the equivalent of level 8 in the first Fallout, even the number of exp you need to reach respective levels were copied from this game). Propably I could grind one more, making the end a bit easier, but there was really no reason to do so.
My final character (you can change his name at character creation, but "Max Power" was so tongue-in-cheek I decided to roll with it):
I decided to tag pistols, diplomacy and lockpick. Pistols were ok. While smgs and rifles deal more damage and have burst fire, pistols is the skill used to operate alien weaponry: reptoid heat rays. And they can deal massive critical damage. Diplomacy helped me to solve some conflicts with npcs and get better deals when I had to pay for aid. Lockpick was useful only several times. I invested almost nothing in mechanic, but there was no need. The final, game-ending skill check was mechanic and I passed it on first try with 30%. Didn't even had to use explosives I spent a lot of time to acquire.
All in all, Omega Syndrome was a fun little game, a very impressive effort of a one man studio. Not very replayable though. I'll write more if I decide to submit a review. Those things require quite a lot of work to do, but I believe RPG Codex should have one. If not here, then where? It's exactly a rough gem Codex enjoys.
