I recently started replaying Syndicate again as well, but I do think the game has some issues.

- Gameplay is very simple, not much strategy involved.

- Missions are pretty much all the same, very little variety.

- Perhaps because I am older now, I know to quickly research to become powerful.

- Enemy AI seems non-existent.

I first bought chest armor for my cyborgs, which increases survivability a lot. Afterwards heart upgrades, which I think helps health recover quickly. Also got mini-guns by level 6 or so. Makes it very easy to deal with enemies.

With that said, still a fun game, but when I was younger I had a bit of rose tinted glasses about the game I think.
