Resident Evil: Revelations was an excellent game and a return to form, harking back to what made the series so great before being dumbed down by action cliches. It successfully combined aspects of both Resident 4 and the first three games.
What didn't quite hit the mark, though, was one of the most difficult boss battle encounters in the series to date -- your encounter with the Scagdead.
The battle itself is already very difficult, but the difficulty spikes more if you fail to collect the right weapon (such as the sniper rifle) or enough ammunition for the job. Not being prepared for this battle may lead to either reloading an old save or restarting the game altogether. Bummer.
