i get that - for me, i’m not in denial, and have no objection or shame in exploiting something where i otherwise simply couldn’t do whatever it was - one example is killing Crawmerax, which frankly i can’t see a way of doing on SP in 2.5 unless you use the ledge - the other creatures just are right on you and wipe you out
As for the armoury, it does have the look of a glitch, but again if so i think it’s a shame they created such a big well-designed space and then gave people no real time to explore it - they should have designed something into the game which, depending on the successful achievement of something-or-other, gave you more time…
Some might not like it, but i’ve sometimes used god mode in other SP games for boss fights because i think most boss fights are pretty boring anyway and can come down to simply getting lucky once rather than huge skill IMO - eg to get past Knoxx on SP in 2.5 is almost impossible because the destructors plus medics mean it’s just too much to take him out…
