Upgradeable weapons and demons to kick everywhere
Get used to the spells and use of the weapons to smash all the demons to get more fun, and addicted.
I've notice a lot of texture pop ups all over the maps and sometimes when you thought there were no more enemies you see an instant group of demons shotting at you, so be careful.
The use of a radar or map on screen would be useful, but is missing, sometimes you just get lost (for example in the forest, that by the way is very dark and eye strainy).
I would like more enemy models rather than the unique pink skinless soldier, that is multiplied by 1000 all over the place, I think there are about 5 to 6 enemy models, but it's ok if you just want to shoot.
Upgrading all your weapons would take you about two to three times of finishing the game. The points adquired are not enough to upgrade your weapons in just one game finish, so you probaly need to go until the Caos mode to unlock everything, but in the process all is fun and bullets, and spells, and bullets!
