Basically the title. It is fun, the guns handle well and offer enough variety. The enemies can be a bit repetitive in what they do but the designs are fun and offer a decent enough challenge without being too hard or easy. The game is quite short tho as each area has only 3 levels and there's only 3 areas I think. If you see it on discount or super cheap I'd definitely recommend it as its quite fun and worth a couple dollars even if it doesn't blow you away
It's all right. I will not call it a masterpiece since it doesn't do anything particularly good or unique but it's not bad. It's very much like the original Doom with a bit more movement. The enemies have a good amount of variety and the weapons are fun to use, although the difficulty and enemy placement is a bit weird. At times the game is super easy and on others it brings every enemy on the screen at once. It's still old school fun and the controls are solid enough that it is worth playing even today, it might not blow your mind or anything but it's definitely worth your time
