Serious Sam: Double D

[fistfulofmetal]

it's a good game. you should play it:

watched that and immediately played.

in one sitting. it's ~ 2 hours long. well worth it. soundtrack is amazing. it's pretty funny. the weapon stacking allows you to make some awesome combos. it feels kind of broken in an awesome way.
there's some INSANE enemies in the game. overall it's a blast to play and well worth the 6 dollars it is on STEAM right now (if you own any of the previous serious sam games)

i believe there are only 4 versions of every gun.

if you go back and do level select all your guns carry over. dunno about new game.
