True. But I don't think he meant the literal flare item. Just a projectile that lights an area.
Btw, I don't think the game is that difficult early. You lose a lot of guys, sure, but the chance of losing the campaign is near zero. Melee monsters can oneshot your entire squad on the first turn, which is a huge threat, but they're not as profitable so more evaccable, and most other missions are pretty winnable. I also think kevlar first is more important than vans because getting oneshot is way too common and it can frequently block a shot entirely. Meanwhile armored shields block like 80% of bullets... it's pretty absurd, which makes sense for a "low-tech" game.
I do think it's funny how much retrieving a single alien corpse can unlock a lab which can result in a 50% tech boost. And yet since the aliens oneshot all your guys, have a very tiny window for landing, perfect reflexes, and enough hp to survive a couple shots, this is actually the most difficult early game goal.
Love the mod and all the quirks above. Only real complaint is it can get a bit grindy against high-hp low-threat enemies like zombies or some outposts you out-tech. But I prefer short but randomized/replayable games in general, unlike a lot of XCOM players.
