This would be an excellent arcade game if you didn't have to walk. Capcom Quest of Dino Stalker! The only Gun Survivor without Resident Evil.
I'm kind of lost in what time the event of this episode is happening, but it seems like it's after DC2...
Here we have the classic, and so loved by me, arcade shooter games! But half of the missions you have to walk on the map, which makes it difficult to walk, aim and shoot at the same time.
Always follow the yellow arrow on the compass to beat the level, of course several dinosaurs will stop you from doing that, so just kill them all!
Be careful that many of these assholes steal your items, especially the "revives", if that happens run after them as soon as possible.
There is also a time limit, you can increase it by doing kill combos or collecting crystals. Some stages don't have checkpoints, you know what that means, right?
About the bosses, there is a pair of T-Rex that appears 3x throughout the game, the others are very original. Too bad the emulator crashed a lot on the final boss.
Finally, Dylan and Paula appear to help the protagonist (Mike), hinted that this happens after the events of 2, that is, they survived!
