Vice: Project Doom is a platform game with driving and shooting gallery style stages as well. There are cinematic cut-scenes between levels, with a secret agent storyline. It plays much like Ninja Gaiden mixed with Batman: The Video Game.

The game has beautiful level designs with great use of color and contrast, and lots of scrolling tricks, including a parallax scrolling train level much like the one in Ninja Gaiden II.

This is a Hardmode hack of an interesting game with cinematographic storyline and different types of gameplay. It is no longer an easy game like it used to be, "gun-levels" can be the test for reflexes and a new weapon selection mechanics adds some changes to gameplay too...
- No more cycling selection of weapons: while standing or sitting player shoots his gun on pressing the "B" button, "Up + B" gives you melee attack, and grenades are thrown on pressing "Select" button;
- Some changes were made to boss rooms on stages 6 and 8 to prevent quick and primitive boss-kills; 5 level boss (tank) can now run over and damage player with its bottom part.
- All enemy attacks deal 5 points of damage (that is 1/4 of maximum amount);
- Small healing item now gives 3 points of HP, large medkit - 12;
- "Gun" drop item now gives 8 bullets, maximum amount decreased to 80;
- "Grenade" drop item gives 2 grenades, maximum amount decreased to 35
- Grenades are no longer "regenerating" by themselves;
- All ammo is lost only on "Game Over" (not when you lose a life);
- "Coins" now give you additional life for 50 of them (not 100), all coins are lost on game over;
- Changed graphics of drop items (healing items, grenades, bullets, etc) and some sprites of the main character;
- Whole game translated to English.
